With the change that has been announced, I'm going to have to give up the topic I guess.
If it's OK to discuss mixers generally speaking, if we can't give links, directories, or "google 1234mixer.com", I don't see the purpose or how it can be done differently.
I suppose people will start creating websites or blogs with lists of Legit mixers and scam/closed mixers to help people keep track of them, like this
one. I think reporting scam/phishing mixers in the scam accusation will also be something dangerous.
No one want to risk getting banned when their intentions were genuine.
