The rule since 2009 has been that you can only Pit the staff for their actions as posters. I find it unlikely that the people who are complaining about that very rule change have forgotten about that rule, so I doubt reminding them would help.
As for the thread itself: it had already been driven hopelessly off-topic, in my opinion. The topic was “What can we do to keep the Straight Dope and the SDMB alive? Here’s one idea.” The second it veered off into “airing grievances about the OP’s past actions,” it was off topic, just like it would be for any other poster.
There have already been two spinoff threads that seem to cover the original topic. so I don’t really see any reason for the mods to reopen the old thread after it had been taken so far off topic.
