Just like the case LoyceV mentioned above. I am not sure the user would have changed and become a reputable member today if he was tagged by LoyceV.
That would have been Trust abuse:
The system is for handling trade risk, not for flagging people for good/bad posts/personalities/ideas.
I feel like most of the users in this thread are referring to neutral feedback when they are saying tagged for being a spammer. I don't think I have seen too many negative tags on people's accounts just because they are shitposter. Some of them got negative as shitposter with some other reasons like Plagiarism or similar offense which could be identified as incorrect use of feedback system as well.
LoyceV, what is your take on neutral feedback? We the forum members use neutral feedback to write anything on a user's feedback page. No matter if it's trade-related or not. Do you think it's an incorrect use of a feedback system?
