On the other hand, while every game is a closed universe unto itself, I'd still not expect to betray some in several games and then have them treat me as a completely blank slate. People don't work that way.

I think lists go to far, especially since there is often debate about whether a certain action was actually a violation. It would just lead to flame wars about being put on the list.
I think posting about people breaking deals is good, that's part of the disincentive to do so. Probably best to keep the ranting down to a minimal level, though. The accused can also give their side of the story...
