He wasn't banned for thinking Buffalo is a viable family. There's no problem with that. If that was the case, NickleCity would be gone too, but since he's a respectful poster, he's still here.
Rooster was banned for derailing multiple threads that had nothing to do with Buffalo..

And even then, he's not truly vindicated, because it's still one article written by one expert against the entire federal government, other equally reputable mob experts, Buffalo turncoats, DAs, and federal prosecutors. And it offers nothing specific other than an "attempt" at a revival. Many other families attempted revivals as well, and it doesn't mean those families are still active. Cleveland attempted a revival in the '80s or '90s IIRC. Didn't work. Rochester attempted a revival in the 1990s. Didn't work. The Trafficantes inducted new members and pushed into Miami in the 1990s as a revival attempt. Didn't work. I assume there are other examples.

And nobody's saying these guys went to flipping burgers. But 95% of reputable sources concede the family has no viable structure left, and hasn't since 2010, at the very latest. The big ticket rackets like the unions were taken away.
