A question about getting a warning

Just got my first warning for playing harassment on the boards, and I feel like they took me the wrong way. Is there anyway to talk to someone about it?

The gist of it was, the OP was complaining about solo queue leaving and I responded with "why are you still here?" meaning "If you hate the game, why are you still posting here?" but I can see how it might have been taken other ways.

Warning or not, is there some appeal process? Most of my warnings are "you posted this in the wrong section" so I've never had to deal with any of this before.
