I want to emphasize just how true this is, in case anyone thinks this is hyperbole.
I managed a pissant VBulletin forum, and moderated a pretty small subreddit. The former got me woken up at 2, 3, 4am with phone calls because someone got banned and was upset about it. The latter got me death threats from someone who lived in my neighborhood, knew approximately where I lived, and knew my full name. (Would they have gone beyond the tough-guy-words-online stage? Who knows. I didn't bother waiting to find out, and resigned as moderator immediately and publicly.)
I home-hosted a minecraft server and was repeatedly DDoS'd. Don't underestimate disgruntled 10yo's.
