I'm not a grammar expert (as the true experts know), but some times things don't make sense to me. The first sentence of your post to Boris is one that doesn't connect with me;
"Seems here you either need to lie to the mods or report the posts." Who do you mean by "you" in that sentence, the troll or Boris? If you are talking to the troll then the first half is OK (the troll lies and gets banned) but the second half doesn't make sense (why would a troll report his own posts?). If you're talking to Boris then the second half makes sense (Boris should report the posts to get the troll banned) but the first half doesn't (what good would it do for Boris to lie to the mods?).
After your explanation I understand you to mean that either the troll gets caught lying, or the users need to report the posts. That isn't what you said though.
