Is adding counter feedback and giving positive trust to someone an appropriate use of the trust system?
Before new system, counter feedback was used to remove red warning message for accounts which were tagged. It can serve to show trust senders that their negative trust is inappropriate and they should remove it (for example, lauda-eddie13 fight IIRC over some words, lauda tagged eddie, 2 users countered feedback then lauda tagged eddie again and feedback was countered again, then lauda decided it is best to remove negative feedback).
@marlboroza: since all negative feedback on OP has been removed, you should probably remove your positive feedback too.
Already done. OP can lock this topic.
