What does mean by involved with hacking? Do you mean these accounts are related to any type of hack or you mean these accounts are hacked? Whatever your beliefs there should be more and appropriate reasons to tag them. Simply change the password at the same time doesn't mean all accounts are hacked or related to hacking. So please describe briefly why do you believe that accounts should get a tag.
After checking OP's trust page i got that his/her account was hacked and multiple tag with proper reference is visible there. It looks really surprising that one hacked account is putting accusations on some other accounts and claiming that these accounts were hacked.
How did he/she know that? Is there any connection between him/her or have personal issues. Its the main fact here. Lets wait for his explanation.
