You could try reading the thread and find out. eddie13 is concerned about your erratic judgement and frankly I am too. Try to scale it down more towards stuff you are an "expert" of, that might help.
Just judging from what I've read in this thread so far, I'd have to agree with you.
Putting a quote of someone's post in your signature doesn't strike me as problematic in the least, especially if the attribution is right there with it.
Suggesting that someone with a valid red trust (in this case for promoting scam exchanges) start off fresh with a copper membership account is very, very iffy advice to give that person. Yes, it might be completely "legal" and very doable, but this would basically allow that person to potentially continue doing shady stuff, and the community would have no warning anymore.
I'm glad eddie13's neg from Lauda got countered. I'd been dragging my feet on the issue because I'm not a fan of counter feedback in general, but in this case I think I would have left a positive had I acted in time. Anyway, hopefully eddie13 and mosprognoz can find some way to bury the hatchet here.
