+1, I've regularly seen Tremor in RP, and haven't had any issues with him.
On the topic of the racism warn - people can change. I've played DarkRP for a number of years, and I've seen people grow up and become embarrassed of them past selves. At Tremor's age, I hope he his capable of growing as a person. A year's time isn't very long for someone to change their habits, but then again based on the interactions I've had with him, he doesn't seem toxic or anything.
