Like most said, both are pretty bad, but i'd go with Slla yer. Even if he picks 69 a goblin he probably won't get banned. I have an account named Revoltjaggex and it hasn't been banned yet, and I've had it for over a year. You can have that if you'd like also.
althought it isnt great pick sllay er 69 a goblin is just ginna get you banned by some noob,probobly the one that got my accuont robin dat ho banned,or possibly the one that got r0bin dat h0 banned lol
