The ones I found and used, are servers where people chat nonsense and when you say hi they will ignore you, and servers where once you join and add roles, onlyfans and random people will message you in exchange for money. Also some servers won't let you in, until you provide ID! Which I'm not comfortable of sharing my ID with strangers. Most of the servers say +18 only, but It feels that most of them are teenagers college or university.
