Roleplay may involve war, revenge, trickery, pranks, and other such things. Despite the rules, I am making exceptions for roleplay. Although It's hard to make rules for roleplay, here's a vague guideline. You may not go around killing people at random (*cough cough* I'm looking at you Isaac Miller). However if it's understood that you're a part of a war, you may need to expect that getting killed is a part of that, and take it in good fun. If you're in a prank war, you may need to deal with a prank that you don't like. If you don't want to deal with getting killed, don't involve yourself in a war. If you don't want to get pranked, don't involve yourself in roleplay, and probably make sure people know that you don't want to be pranked. Do not do something that you don't think the other party would take in good fun. You have the option to not involve yourself in roleplay, and please do not involve people that don't want to be involved. When a server allows roleplay, everybody may need to be a little more flexible.
P.S. to put into perspective how small Minecraft books are, this paragraph would take like 5-6 pages, I'm not even kidding, it's absurd.
