On other sites, “100% verified” is just text. Here, verification is a real process and the proof is public: every profile shows the date it was last verified. If the re-verification deadline passes, the badge is downgraded automatically.
At sign-up, the advertiser confirms she is over 18 and that the photos are her own. The listing stays hidden until a moderator approves it by hand.
Every new photo is compared with the photos of all other listings on the site, and the moderator sees any match before approving.
The badge shows the exact date. Reports are investigated within 24h.
