While I don't have the "Riot" prefix (which is every Rioter's choice), I am recognized fairly often, so perhaps I can field this from at least one perspective.
I play quite a bit of solo queue, though I've been doing 5-mans more often these days. I find that, for every jackass who does things to spite me simply because I'm a Rioter, there are three or four that are awesome and make the game a great experience. So I figure my odds are pretty good.
We do tend to have thick skin, but toxic behavior directed at us will inevitably affect us. But it's part of the job; it's part of being able to interact with you guys directly. We have a responsibility to maintain our composure, and to not lash out. Sometimes that means that we stop playing for the day, and sometimes that means we stop posting for a while. Each person is different.
