Don't do that... Retaliatory feedbacks always result in more negative feedbacks. Not to mention that your feedback is marked as "untrusted" and doesn't count for anyone's trust score. So, you're just attracting more negative feedbacks.
But it doesn't really matter. Account buyers/sellers usually get many negative feedbacks and they stay there. Buying accounts may not be against the forum rules, but it is very untrustworthy from the eyes of the community, so we all agree that the user deserves negative feedback. Your account is "useless" now (assuming that you only bought it to earn money).
I'm not doing anything against the rules, they say i can buy and sell accounts. But referrals aren't allowed and Steamtyme has a referral link in his profile, so, who is the bad guy here? Who is against the rules? and who is abusing the system?
But if people want to abuse the trust system then expect a consequence for it.
i will leave this here for the record;
Trust system abuse:
