Earlier today I had a conversation with wrbtrader regarding this topic, and while I won't reprint anything he said out of respect for privacy, I will repeat a few things I told him. I checked most of brass_trader's IPs and there's no overlap, but that may mean nothing as people often use proxies when they return.
So we've got 2 issues here -- is someone the return of a previously banned alias, and is someone making egregious posts now. Regarding the former it's important that you provide me with corroborating evidence. That means distinct comparative examples of writing style, grammar, spelling, eccentricities, etc. So please don't hit the Report button on someone's post and say you just "know" it's so-and-so returning. Tell me specifically why.
Regarding someone making egregious posts now you are welcome to hit the Report button and point out problems or issues. I will be glad to take a close look at specific concerns you have, but I don't want to kick people off of ET for unpopular political opinions or wrong groupthink.
Thanks.
