At last, my name is listed here as well! I feel honored to be part of this select group! /s
WTF are you guys doing over there? 
Ratimov's plagiarism loophole has been discussed before, in several topics. He didn't get banned for it, which means Mods think it's okay. If Mods think it's okay, who am I to disagree?
Bad and rude language is allowed, and shouldn't be a reason for negative feedback either. The same for retaliation feedback.
My take: both of you should remove the negative feedback. If I would loan either one of you $100, I'm pretty sure you wouldn't scam me. That's what the Trust system is for, and that means negative feedback is unwarranted.
You guys don't like each other: that's okay! Agree to disagree. Ignore each other. Or get a beer together. Find common ground instead of drama.
To quote upper management:
The system is for handling trade risk, not for flagging people for good/bad posts/personalities/ideas.
All that being said, I still discourage retaliatory ratings, and with these changes I encourage people to try to "bury the hatchet" and de-escalate rather than trying to use any increased retaliatory power you now have.
