Undeserved Riot Mystery Gift

I recently received a mystery gift (Snow bunny Nidalee) for good behavior and I believe that this might have been a mistake. I've been trying to be a positive player in recent months, but over all I'd say that I can be a mild to severe toxic player. I get frustrated when people can't see things as clearly as I believe that I can. I tend to rage, swear, belittle, and become extremely angry sometimes when people make bad calls, chase when they should be going for objectives, or ignoring objectives. I've had warnings, temp bans, and most recently a chat restriction, for something like 50 games. I realize these things about myself, and I've been trying to play less toxicly and have a larger positive impact. But, I do not think that i deserve a mystery skin gift for good behavior because I don't think I'm completely reformed, and I don't meet the criteria set forth for getting one.
