P2P seller ads restricted to me

lately, i bought some USDT with a pleasant worth from a number of vendor, however i can't buy from them anymore, the advertisements says RESTRICTED and when i click on, binance says "Sorry, you don't meet the necessities set by other events"

however there's one pattern :

1. they all the time request me to send a proof of cost by way of whatsapp
2. after that, they ask me why i buy 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 much less recognized trade aside from binance, like BitxEx, Bitec and IDO (idk if its scam or not, i never attempt them)
7. they all the time ask, if i want more 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, however all the time submit a far larger worth
10. their account is have an excellent status
11. i never obtained scammed by them
12. they are VERY polite

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