Will this add friction for real providers and consumers?

No. Rupt starts conservative, and a real user clears every check without noticing. Only a borderline signup or lead gets a code by SMS or email. Crexi rolled out at 1 to 2% of traffic, and its customers saw verification as a feature, not friction.

We already verify phone numbers.

Keep doing it. A burner line passes every phone lookup as valid, active, mobile and low risk. Rupt links the accounts a number is verified on, so a burner that passes every lookup still ties six identities together, and the device behind them ties the rest.

Our scammers are humans, not bots.

Most are. The realtor scam ring typed every message by hand and set off no bot check. Reuse gave it away: 19 identities on one browser, 18 signups on one IP, 6 on one throwaway number.

Do we still need our moderation team?

Most teams keep people in the loop and use Rupt to decide what reaches them. Obvious scams are held, clean traffic never enters the queue, and what is left arrives with the linked accounts and device history attached.

Can it stop banned users from coming back?

Yes. A new email, a new number and a VPN do not change the device. Rupt links the return to the banned account and challenges or blocks it before it reaches your users.

We run a job board. Is this the right page?

Job boards are marketplaces, and everything here applies. Candidate fraud has its own page at /hr, with fake applicants, one person behind many profiles, scam postings and recruiter seat sharing.

Plans start at $99 a month with 20,000 evaluations included, then $0.005 per evaluation. Cost follows the signups, logins and messages you check, not your user count, so you can measure everything before you enforce anything.
