A friend got blocked from promotions

So yesterday a good friend of mine was blocked from collaborating in the haloween promotion because his account was inder danger assessment for suspicious activity. He has never accomplished something suspicious, just shopping for and staking crypto as well as collaborating in promotions. When he contacted help, they advised him that he's underneath investigation however they will't inform why is that they usually additionally stated that he will never be capable of take part promotions from this point on. No explanatioj given..... Anyway, 1 hour after that he managed to hitch another promotion.

Can anybody shed any mild on this case? Has this occurred to anybody else before?

I know this guy personally and know that he has never carried out something that would rely as suspicious and the whole state of affairs makes me doubt that my belongings are protected with binance, especially since help truly didn't supply any specific info on the case.

Thanks for reading and have a pleasant day everyone!
