I have all the necessary evidence so that they can ban it from the site, could a moderator or supervisor intercede?

You can report a user(s) via the [support hub.](https://www.speedrun.com/knowledgebase/supporthub/report-user)

I already did it and no have answer since 1 month...

You won’t get a notification that something has happened to a user you reported (i.e. if they were banned or not). You would have to check the user you reported’s profile to see if they are banned or not. If they aren’t, just DM @starsmiley about your situation. She’s usually the one who bans users.

I need to report a user as a cheater and misuse the site.
