What are we allowed to do in rap battles?

I noticed that mod ding on this site is cracking down on all the racism and other forms of "hate speech". What am I allowed to call my opponent (the fake Tyrone and rational gayman). 

As a black man (see picture), it is part of my culture to rap battle people. We often can get pretty nasty in rap battles and say hurtful things, but it is all in good fun. Like can I bring up that RM was touched inappropriately by a close relative? Or can I call the fake Tyrone a cracker . I need to know so I don't accidentally violate a rule.

You can get banned, shut up and cry like all who face me in a rap battle shall do in the long run unless they enjoy feeding me wins.  In all seriousness I would have still slaughtered your flow, rhyme scheme and quality of puns had you done that and remained here for all rounds.
