I have banned him and rolled him back, along with another player named killerbenz. I think everything should be fixed now In the future you can post this in the report section so it can be seen and dealt with faster

Thankyou and sorry to bother you again but he banned me from the server.

you were banned by appleguypro for illegal trading, you have to make an appeal in the appeal section of the forum

What does illegal trade mean?

it means you sold or bought items that are illegal to trade. Usually it's dirt and buckets.
