I think it depends on the topic that it was used on.
Gimsolver, this belongs in Help, Community Made Guides is for guides and I suppose it could go in Devices, but that’s twofoursixeight’s choice whether or not to move it.
No, I think that Jeffo allows a few psas as long as they are very important like the 2-FA. But he will remove anything unnecessary. I would suggest just making GKC psas to be safe. GKC psas are allowed.
PSA’s were created when GimAi created one about the forums. Then, it grew a little off-course and became about other topics. After that, suddenly, there was a rush of PSA’s, FA’s etc. from new users (don’t know why) about the forums that were all basically restating the TOS and FAQ.
This probably refers to old-styled PSAs which are repetations of TOS and FAQ. @wingwave explained perfectly what happened to old TOS oriented PSAs very well.
And I suppose this refers to PSAs today as they contribute to the GKC experience.
Again, I marked wingwave as the solution as it perfectly explains the descent of Forum Psas, fyi.
