Since litterally no-one here has answered your question properly, even though you have not been online in three days, here is what has happened in somewhat cronological order:
people made some discord servers for discussing RP to replace the SA server, or just simply to assist in having a place for RP discussion. (something you are aware of but im listing it anyway) one major one is still alive and the others have pretty much all died as far as im aware.
TIE began preparations of a reformation, which as stated by brank here, have come to become a reality.
(which is real cool! finally a proper multiperson faction is alive again!)
However, im not sure how active it is, since i appear to not be in the server anymore.
Bloodcult war vs everyone else started, people instantly began far too much complaining over it due to concerns over things in the event.
Multiple events have begun, and some ended, Tson's one now entering its second chapter for example.
Faction RP has become less populated, but far more interesting i feel, and in fact id say character and overall story related RP is better than ever.
Around five members of the RP section left, and i won't go into why, its a long story and im not going to start it again. It should be rather obvious who the people who have left are.
And that's about it, i theorise that after Walt goes to PAX this RP section may see an influx of new people! which will be interesting indeed. Although to be honest im more interested in the competitive MP side of such an influx, which i ofc won't go into here.
As for the current state of the RP section, most of the good/great RP is only really from a small number of people, which isn't that bad considering that you only need two people to do RP.
But either way, thats all i can think of off the top of my head, im sure you could ask someone who actually reads everything to learn all the info.
