Just a few ideas but: Minecraft Rant - hackers , griefers, pvpers, noobs (not newbs there is a differnece)(noobs dont read the rules and suck but newbs are good people that read rules but they were just late to the party) showoffs, more trolls, spamers, scammers, people who play minecraft cracked version
Let's not forget the people that believe the YouTube comments that say "Get your free MC Premium account!", then they get it, find out the account has viruses/hacks/mods/malware, then hate on Mojang, even though they didn't buy it from Mojang.
I love reading some of the replys to those who post those bytl links "does that come with a free virus or is it a seperate download" but I hate it when those free account links are the top comments (I always flag them for spam)
I do the exact same thing.... I once gave a long and complex analysis on how it technically was piracy, then the people that post those flagged for spam and disliked it. One of the comments I got: "How is this spam???"
those people work together plus im betting those free "accounts" also installed some program that automaticcaly likes those comments using your youtube account with out asking you
Don't forget the people who post Auctions while using Nodus then rage that they got banned without proof.
