So in summary only Hina is leaving right now all the other post are for long graduated WACTOR members stating they left the company a long while ago and have been in legal dispute with the company since, seems they are all coming with this statements simultaneously as some form of solidarity or to call out the company, a while ago there was supposed leaks of the terms of the wactors girls contract and they were insane on top of the already know no compete clause that forced the girls to stop activities in any past life, there where yers long NDA after the end of the contract and multiple really vague clauses giving the company power to declare a breach of contract and sue you for the damages, about the favoritism thing, long has been rumored that one the girls
Mitsurugi Lia is either wife/girlfriend/cocksleve of the CEO and she get favored treatment because of it, she did a livestream about the accusation recently where she didn't deny nor confirm any of it.
The height of the current drama started because the 2 biggest members (Hina and Luna) went on hiatus without much word from them and then their pl where found and people saw hints that the hiatus might not be voluntary, eventually the information spreaded to twitter and one of the girls (Luna) closed her pl account do to many tourist flooding in, there was apparently a lot of infighting between the fans about this whole situation due to people on twitter and some dramatubers/twitters also reporting on it got a lot of hate for it, some people want the girls that are left to leave but most people point out the current 4th gen has 2 year contract and are pretty much trap some people tried to target the hate toward the CEO but the Lia stream redirecting a lot of hate towards her and the whole drama about the girls pl being "doxxed" pretty much killed all the steam this had.
This is my limited understanding of the situation I know Spanish but the information is being pass around in so many different places that I cant really know the whole context, this is only what I could gather by reading the VT threads from a couple weeks ago, if someone if more up to date or know more of the whole picture feels free to share or correct me.
