When you see users using group specific terms like "d0ughnut", "hydrate", troll, etc. see if they are also exhibiting any of these classic warnings signs of unsafe groups and cults.
Potentially unsafe groups "come off very nice at first, they go for vulnerable people who are looking for answers, lonely, what you'd call 'normal people.' They're very good at what they do and can get people to believe anything. You might think you'd never get taken in, but don't bet on it. "
