Ok so lately my friend got banned for "Being associated with Exploitative Accounts".

Can someone even explain what that means?
Suppose a person talks to an Exploitative account and is a friend with it but doesnt know the truth about it, that would get him banned?

Please explain how does someone get "Associated with Exploitative Accounts"
