I don't really understand some admins here.
The user shared the hlstatx chatlogs as evidence, but from there you can also get rulebreaker's username, steam ID.. and that's literally everything you need for a gag.
If you don't wanna handle stuff cause it requires more work (that was one more click..) and it bores you, just let other admins do it. The user took his time to report, he wasn't forced to. Let's not vanish people's efforts, if we can avoid that.
