I think we need to compile a list with VTubers you need to stay away from. In the last 5 years, the hobby was infected with an alarming amount of grifters, stacies and other sluts and sexpests that do not deserve positive attention or need warnings on them for previous and current transgressions.
I understand most of these will be (ex)NijiEN, there are still outliers and other indies that try to hide themselves under new names and new faces.
This is not an invitation to harass them in their chats or their DMs. It's best to leave them to their own devices. But nobody wants to accidentally follow and start to like a lunatic that backstabs friends and drives others into suicide.
The people I'm thinking about are people like
Sinder
MarieFD
Elira
These are obviously evil and show no remorse for their wrongdoings and will sin again

The ones I'm not thinking about are:
Ike Eveland
Mikeneko

Micheal is just a little menhera but there was no crime, just some petty drama.
Ike has been forgiven and it was pretty clear he had no big and conscious part in Nijishitshow.

This might be a tall ask, but we all benefit from orderly conduct and being informed about the people who are simply evil to the core. You dont need to waste your emotions or your money on them.
This is not for drama. You are not a fucking celebrity gossip magazine writer. There is a clear consensus on who is actually evil.
