i've been overwhelmingly convinced by all the evidence you've posted to ban him from my server
get out, you're not helping at all to the topic except basically telling the op that they're dumb for not providing any proof.
Nowhere does it say that he has to provide proof to back up his opinions.
it would be okay for me if it was like, a large and complete text describing the exact problem. i would believe it for the effort he would have put in the OP. but this is two sentences. it doesn't convince anyone at all.
