P2P seller ads restricted to me

lately, i purchased some USDT with a pleasant worth from several seller, 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 different parties"

but there's one sample :

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 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 point me to attempt Futures, especially with ETH
6. they all the time advocate me some less recognized trade aside from binance, like BitxEx, Bitec and IDO (idk if its scam 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. some of them says will supply me the identical worth, but all the time submit a far greater worth
10. their account is have an excellent popularity
11. i never obtained scammed by them
12. they're VERY polite

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