Although "they fucked around and found it" from management is still best theory on what's going on, I thought of an interesting rrat that I don't think I've seen anyone else suggest.
What if they failed on opsec, got doxx'd, and are hiding out or relocating because the threats looked viable? Doesn't quite fit with Magni still posting on his side twitter, but let me provide a quick example:
https://warosu.org/vt/thread/53436369This was during prime SEAhours so I'm sure it's a literal child on their phone trying to be edgy on 4chan. It could be the case though that someone /here/ or with a similar mindset really went after the two specific homos that collabed with HoloEN members. It would at least explain why the announcement doesn't mention suspension even though they did the last time with Vesper, or why The Cause was so tight lipped about it.
