Well if you didn't really want to report him, you wouldn't have brought it out to the public, man do what you have to do you know whats right. "report him" he has broken the rules there are many ways he can get back into the community and 1 is not evading..... What he should of did since its been a year except for evading he should have tried for a high pardon now all his chances just might be ruined.
You could always get someone to do it for you or PM a moderator to look in to so he doesn't know it was you. Withholding the information can look just as bad in black and white so you're also covering your own back.
Feel free to tell us or not.
If he scams someone though, just know that you could have stopped it and you didn't. It's likely we'll eventually get him anyway.
