It's really annoying that Royalmix would just exit scam like that, but I think that trying to maintain a list of all "scam" mixers is going to end up being way too long, since you will also have to include every single phishing domain as well.
Makes you tear your hair out really.
I'm not sure if it was a good idea to remove RoyalMix guarantee verification from my site though, what do you guys think?
