I have an online RPG game which I'm taking seriously. Lately I've been having problem with users making bogus characters with bogus names, just a bunch of different letters. Like Ghytjrhfsdjfnsdms, Yiiiedawdmnwe, Hhhhhhhhhhejejekk. I force them to change names but it's becoming too much. What can I do about this?
Could I somehow check so at least you can't use more than 2 of the same letter beside each other?? And also maybe if it contains vowels
