Persona tackles AI-powered identity fraud as high-velocity attacks double year-over-year

Persona, a San Francisco-based identity verification and fraud defence platform, has released data showing identity fraud is becoming more sophisticated through AI and automation. The company found that devices associated with high-velocity identity verification attempts more than doubled year over year, whilst attackers' devices were linked to 1.5 times as many IP addresses as legitimate users. High-velocity attacks involve five or more verification attempts within two minutes, with fraudsters making minor changes before resubmitting applications. Devices cycling through 10 or more IP addresses increased eightfold, often using residential proxies. In response, Persona is launching new fraud prevention products, including a fully managed Fraud Fight Flow and enhanced tools to detect AI-generated content and stolen identities. The platform serves organisations across fintech, marketplaces, and AI platforms in over 200 countries.

Reddit's Persona age verification: what B2B marketers should watch.

Reddit's Persona age verification: what B2B marketers should watch. Reddit's Persona-powered age verification is expanding beyond NSFW gates. Here's how the ID-check rollout reshapes account trust signals for B2B marketers. Reddit is now pushing verified users through Persona, the identity vendor it picked for its age-gate rollout, and the checks are already spilling past the NSFW walls they started behind. The UK rollout landed first under the Online Safety Act, then expanded across other regions with age-assurance rules, and users on r/RedditAlternatives are actively hunting for platforms that don't demand a selfie or an ID scan to view mature subs. If you run a B2B marketing account on Reddit, this looks like somebody else's problem. It isn't. The verification layer is quietly becoming a trust signal Reddit can use anywhere, and the second-order effects on how your posts get treated are already showing up. What actually rolled out. Here's the concrete version of events, based on Reddit's own public disclosures and coverage in The Verge and TechCrunch: * Reddit selected Persona (a private identity-verification company, not Palantir; a common mix-up) to run its age assurance checks. * Users in the UK are prompted to verify with a selfie or a government ID before viewing NSFW subreddits or posting in some mature communities. * The EU is next under equivalent age-assurance rules, with more countries following as similar laws pass. * Reddit says it does not receive or store the ID document itself; Persona returns a verified/not-verified signal plus a date of birth range. * Reddit is also tightening what non-logged-in and unverified traffic can see, part of the same protecting communities from scrapers push announced in modnews. On its own, that's an NSFW-access story. The interesting part is what the verified flag becomes once it exists as a persistent property of an account. Why a verification flag matters for B2B accounts. Reddit already uses a stack of trust signals invisibly: account age, karma per subreddit, posting cadence, IP history, device fingerprint, past mod actions. Verified age is a new signal in that stack, and once a platform has a signal it tends to use it in more places than it originally announced. There is a pattern here worth naming. * A verified-age flag is expensive for spammers to fake at scale. Farms of aged accounts get much more expensive if each account also needs a real human with a real ID on the other end of a selfie prompt. * Reddit has strong commercial reasons to lean on that signal for ranking, filtering, and access decisions well beyond NSFW gating. * AutoModerator, subreddit-level filters, and the For You feed algorithm can all consume a verified flag without any user-facing announcement. So the practical question for a B2B founder isn't "do I care about NSFW subs". It's "is my account going to end up on the wrong side of a verified-vs-unverified split in the next 12 months". Second-order effects to watch. A few things to keep an eye on as the rollout expands. None of these are confirmed policy yet; they are the plausible next steps given how platforms typically use identity signals. Reach differentials. Subreddits with active mod teams have historically added AutoMod rules that penalize new or low-karma accounts. It would take one config line to add "unverified" to that list. Expect some mid-size subs to try it. Ad account requirements. Reddit Ads already asks for business verification. It is not a leap to require personal verification on the operator account behind an ads account, especially in regulated verticals. Mod tool gating. New moderator invites and mod actions on certain subs could quietly get gated behind verification, similar to how X-formerly-Twitter has tied features to paid checkmarks. DM deliverability. Cold outreach has always depended on account signal quality. Verified accounts sending low-volume, high-relevance DMs are likely to see improved deliverability relative to unverified ones. This is the same pattern Bazzly saw when SPF/DKIM/DMARC reshaped email. Scraper-visible content shrinks. The May 2026 scraper crackdown already narrowed what unauthenticated tools could pull. Age verification adds another axis on which Reddit can decide who sees what. What to do this quarter. Nothing dramatic. A few concrete moves that hedge the risk without over-rotating: * Verify your primary operator account in whichever region you're posting from, once Reddit prompts you. Skipping the prompt is not a neutral choice; it's an opt-out that may cost you later. Reddit has been clear that document data isn't retained on their side, and Persona's data handling policy is publicly documented. * Don't verify burner or throwaway accounts. The whole point of a burner is that it isn't tied to you. Verifying it defeats the purpose and links a real identity to an account you may want to walk away from. * Diversify signal sources. If your Reddit strategy is one aged account posting into three subs, a single trust-signal shift can kneecap you. Wider surface area of legitimate accounts, each behaving like a real person, is more resilient. If manually watching subs for buying intent is eating your week, Bazzly can do the watching so you spend your attention on actual replies. * Track post-reach deltas. If a subreddit's reach for your posts drops sharply after the verification wave hits your region, that's a data point worth logging. Set up Reddit + Slack alerts on your own brand mentions so you notice the delta in real time instead of a month later. * Watch modnews. Reddit typically pre-announces filter changes in r/modnews and r/reddit before pushing them platform-wide. The signal for "unverified accounts get downweighted" will show up there first. The bigger picture. Reddit is doing what every large social platform is being pushed to do: bolt real-identity infrastructure onto pseudonymous accounts. The near-term story is NSFW compliance. The medium-term story is that verified vs unverified becomes another dimension of account trust, alongside age and karma, and it starts influencing what your posts do in normal B2B subs. If you treat this as an NSFW policy update you'll be caught off guard when the flag starts affecting reach in r/SaaS. If you treat it as the next trust-signal expansion, you know what to do: verify the accounts you actually operate, keep behaving like a real person on them, and watch the reach metrics for the moment the algorithm starts caring.

Persona partners with Chainlink to enable reusable identity credentials across blockchain platforms

Persona has partnered with Chainlink to power compliant on-chain identity verification through the Chainlink Automated Compliance Engine. The Cross-Chain Identity framework enables institutions to verify users once with Persona and reuse those credentials across blockchains and protocols without duplicating KYC processes or exposing sensitive data on-chain. The system attaches verified credentials to users' wallets, allowing participating platforms to check validity and approve users immediately whilst keeping personal data off-chain. This addresses a key friction point as traditional financial institutions move into tokenised assets, a market projected to reach $10–16 trillion by 2030. Founded in 2018, San Francisco-based Persona serves crypto companies including Ripple, Bridge and Bitgo, operating in over 200 countries and territories.
