So what do you do if you think someone's cheating, but they've been cleared up as not on here?

Take a demo and email it to the admins. Or get ahold of one of the admins and have them spectate. Just because someone hasnt cheated in the past doesnt mean they wont in the future. There's no immunity, the same rules still apply.

or just post the demo here. because you think its worst dod player.

i've hacked on cdrive server in front of diamond and akarma and they didn't notice me. Whats that considered?

That you suck at dod

i've seen bad cheaters. they like to run into walls a lot.

same.. seen hackers with negative ratios.. dont know how that is :(
