Update:~
Rmcdermott927Left negative feedback for an opinion, the left the forum. I'll remove my exclusion when they come back and remove the feedback.
I think this one deserves more of an explanation. A week ago, they left this feedback:

The
Reference link doesn't provide any evidence for this
opinion.
Even if this would be true, it goes directly against what I consider
correct use of the Trust system and it's a clear violation of theymos' guidelines:
The system is for handling trade risk, not for flagging people for good/bad posts/personalities/ideas.

On the same day Rmcdermott927 left negative feedback, he posted this:
Leaving the forum until some of the trash is cleaned up, if I ever return, which is unlikely I will sign a message.
Rmcdermott927 was on DT1 with Strength (0), my exclusion removed them from DT1. I will remove my exclusion if they come back and remove the negative feedback for suchmoon's opinion.
It's okay not to like someone!To quote myself:
Be the bigger man!With great power comes great responsibility (
source unknown). Especially when you're on DefaultTrust (or if you want to be on DefaultTrust in the future), you shouldn't (ab)use that power by leaving (negative) feedback when someone does something you don't like. Your Sent feedback is what others use to judge your judgement.
If someone on the internet is mean to you:
boo fucking hoo! Use the Ignore button, and forget about them.
