As User A, I will have a counter under my name like so:
obnoxiousness: -7.5 (9)
the number in () will portray the number of users who have given user A an obnoxiousness feedback.
1. The larger the number, the more serious the accusations are.
2. The final obnoxiousness level can scale more rapidly if the number in () is larger, or more slowly if it's smaller. Thus, the number in () can be a multiplier as well.
Yeah, I can already imagine the amount of minus obnoxiousness points some people are going to have based on their history in the forum and personal problems with other users.

I understand.
If you get a bad vote for obnoxiousness, I guess there isn't too much to do about that, but to expect that if this vote is not justified sooner or later this will be offset but contrarian votes, weighted or not.
If such a system is implemented, there has to be a way to counter the problem I have stated above. I would never want my profile to get painted with negative obnoxiousness only because I had a heated argument with a high-ranked member because he didn't agree or like my point of view on a certain matter, nor would I want to have such results for trying to expose a high-ranked member for either breaking a rule, being involved in something suspicious, or doing something such as posting AI-generated content, etc. Even if the account is bought, it will still be able to ruin my profile based on the system and the rules we have discussed so far.
