You'd THINK, after this happeneing MULTIPLE times already, Cover (or hell, any other corpo) would've figured this shit out by now.
Duh, an empty fresh channel gaining a massive influx of subs in a short time seemingly out of nowhere will get flagged as suspicious (because in most other cases, that are not rare exceptions like Hololive talent debuts, there actually is often foul play involved, and the algo doesn't make that fine distinction) and have a high chance of being culled.
The obvious solution is to not release an empty channel with no content, but to prepare some stuff beforehand like teasers, trailers, music, MV's, whatever, that they can put on their channel so the algo doesn't think "mmhm why would so many people sub to an empty channel? must be bots, let's cull them!" and instead just think "wow, those few short videos that channel released must've been really good, ok that's an understandable organic reason for their fast subgrowth, everything's a-ok here!".
Of course better preparation is still no guarantee that you won't get hit by a random subcull, but at least it lowers the risk massively. This should be basic 101 knowledge stuff for any company that basically makes their living off youtube, and they still fuck it up more often than not.
