I agree with Red. He said what I was going to say--- But, If the people you roleplay with do not understand the basics of getting in character, warn them you are about to do so, What I say usually before I role-play is say:
"WARNING: I am NOT my character. I WILL get VERY into character. If you do not agree with my characters actions, do not take it out on ME personally. Just dislike how my character acts. Now, Lets RP!"
Give them a heads up, saying Zuberi is rude, crude, and a jerk. If they can't read the fine print, then there isn't a point to rping with them. Because they are immature. But if they ask you to tone it down a bit, don't argue and say
BLAHHHH IM JUST RPING! BLAHHHH
cause it isn't worth getting banned over. Just say alright. And continue... At a toned down rate. Because people ARE like that and sadly you have to change a bit because of it. :/
