P2P seller ads restricted to me

just lately, i bought some USDT with a nice worth from a number of seller, but i can't buy from them anymore, the advertisements says RESTRICTED and when i click, binance says "Sorry, you don't meet the requirements set by other parties"

but there's one pattern :

1. they all the time request me to ship a proof of cost by way of whatsapp
2. after that, they ask me why i purchase USDT
3. i stated it was for USDT arbitrage
4. they all the time say "your profit could be very small"
5. they all the time level me to attempt Futures, particularly with ETH
6. they all the time advocate me some less recognized trade aside from binance, like BitxEx, Bitec and IDO (idk if its rip-off or not, i by no means attempt them)
7. they all the time ask, if i want extra USDT
8. principally, they all the time says doesn't have USDT left to sell
9. a few of them says will supply me the same worth, but all the time publish a far greater worth
10. their account is have a superb status
11. i never acquired scammed by them
12. they're VERY polite

virtually EVERY vendor that sells with good worth have that pattern, i have to know what is occurring proper now. lets talk about
