Krissovoj.com, is it suspicious?

Like, if i buy 20 pts on that site (i know it works, bought from it before)
But if i buy 10 B-Cards aka 10k cps something to ONE account, will it be suspicious? Like, i know it's not really legal what he does, but can it affect my account? or should i buy the cps to another acc?

You can buy them to one account.

its legal

The cards that kriss is selling were bought by himself, so they're actually legit. Nothing can go wrong.
