There's a difference between 'Hey, stop doing this or I'll report you to the Titans/Magistrates/Tom!' and 'Hey, this goes against the rules, you mind correcting your behavior please?'. Basically, don't threaten to report people; there's nothing wrong with discussing a rule and asking that someone stop breaking it. If they refuse to cooperate, then report them. But report them without posting about how you're going to report them. You should never need to tell someone 'i'm going to report you'.
