‘If you suspect someone of being a troll, please don't accuse them publicly on the discussion thread (if you're wrong, you could cause untold hurt; if you're right, you'll merely be giving them just the kind of attention they're after).
Instead, please report your suspicions to us (either by reporting a post of theirs or by mailing us at [email protected]) and we'll check them out.
Please bear in mind that we'd rather err on the side of being taken in than of accusing a genuine poster who's in need of support of being a troll’
From the guidelines. Just saying
