? Extremely thin-skinned whiners. When a person would comment on a video "did he died?" when someone, say, falls off a skateboard, there'd be plenty of people whining about it. Obviously it's a joke so either ignore it, laugh along, or move along.
? Junior / Closet moderators. Regular posters (as in the same ones who aren't mods) constantly posting "this will be locked" "this is against the rules".. gotta love certain sects of a community where people act as police toward each other, but I believe this is done in attempt to brown nose one's way to modship too. This isn't the only forum either.
? Web admins who complain about Adblock. Sorry cuz, it was inevitable. Personally I don't feel like getting the [censored] scared out of me having my speakers on when browsing random website with someone shouting that I can win a free iPad.. merely because a website needs ad revenue to run. Perhaps doing ads a little more subtle like Gmail instead of the intrusive and annoying ones that people just might block might be a good start, no? Adblock is here to stay, I'm going to keep using it, and if web admins don't like it, time to be more innovative then huh?
? Traffic shaping / port throttling. Look, ISP, you already get my money and now you even get away with monthly bandwidth caps, all because you lazily wanted to avoid upgrading your infrastructure to something more modern and continue banking off a 10+ year old system that's obviously either pushed to it's limits or not as efficient as other methods. However, trying to slow my connection down for certain websites or throttle certain ports and further hinder the connection? Bite me. If someone's doing something illegal, eliminate their service. If not, leave it the [censored] alone.
Probably more but kinda getting bored with the topic.
