I've been RPing since 2006 or so and I've never gotten hate comments. Neither have any of the people I play with, save for a tiny handful who deserved it for their terrible behavior.

If you aren't a jerk to other people and you aren't an atrocious writer/horribly OOC, you'll fly under the radar. And honestly, it's pretty narcissistic to think that people will care that much about you to give you crit or praise unless you're really, really good or really, really bad. The vast majority of people out there don't care enough to bother.
