I don’t think they actually want to ban anyone really - they just cave to mass reporting. The business model wants as many members as possible, so banning en masse negatively effects that main aim.
The way Twitter works seems to bring out the worst in people in a way that say Facebook and Instagram do not (the mass pile-on phenomenon is enabled by Twitter’s functionality. It’s much harder to create a mob on other platforms).
Personally I think it should be allowed to die a death, but that would take ‘Blue ticks’ ceasing to use it.
I have an account but I don’t use it (more to stop someone else impersonating me than for any other reason)
There is an enlightening Joe Rogan podcast episode with the Twitter founder and a twitter lawyer and Tim Pool. Pool asks pointedly about Megan Murphy, by name, and the lawyer gives a master class answer in ‘admit nothing’.
