Banned on Bumble, Tinder, Hinge within 12 days of creating new accounts

Interesting info for the banned among us.

I was previously banned on Bumble, Tinder and Hinge.

So, I got a New phone, New number, New pics, but I used the same Wifi IP. I reinstalled the apps and began getting a huge number of matches - it was looking good. I definitely wasn't shadow banned. I upgraded all my accounts to short-term premium (because I did expect there was a likelihood I'd be banned, so didn't want to waste too much money).

Tinder banned me fastest. Within about 4 days I was banned. Bumble was next and that took 7 days. Hinge lasted longest at 12 days. I was being very polite to members so I don't think my ban was behavioral as far as I know.

I'm guessing at this stage that these apps track you through either your IP Address if you log onto the same wifi you were banned on, or facial recognition. I'm also wondering if there's humans behind the scenes that recognise banned members after a while and re-ban us. There could also be paid members who just flag and ban profiles for fun.

I'm planning on trying again with a VPN this time, and try using pictures that don't give a full-on view of my face, and sunglasses pics to try and fool the facial recognition. Any advice?I must be on some crazy blacklists.
