use common sense......
IF its a big trademark name they can simply take the name from you = you are screwed.
Say you regged thehun.whatever (they could simply demand that you give them the domain).

Lesser names you would have no problem, but at the end of the day check the systems TOS and/ check with them.
Im sure that they would rather have you send the traffic to then and not someone else.
