1. Twoo & Badoo use the exact same database, marketed as separate.
2. Gain new users through false advertising - "this person invited you to join" emails.
3. Uses inactive accounts / silent messages to bait people back in "X wants to chat" etc.
4. Posts obviously false alerts e.g. "10 new notifications" for likes you got 1 year ago.
5. Keeps charging your card; they say you can cancel "at any time," but in practice the site resets to active next period and keeps charging you with no overflow. I left the platform for 6 months, had to threaten with legal action for the charges to stop after "cancelling" several times. No refund. The company should be sued for exploitation.
But at least it has a search function so it has that over Tinder. Paywalling attractive people is not a big deal.
