I'd say don't be shocked... Internet life has just as many feuds and problems as real life.
I got downvoted by the same stupid reasoning in the comment above. The solution is to make this place so incredibly large and full of people that the chances of bumping into these people slim to none. And good ridince right? Sure they have large votes but who needs the drama right?
If there are millions of people the likelihood of ever being on the radar of a @liondani or a @themarkymark will be almost 0 and that's probably the best thing to happen to this experience. Right now we're a small town with small town drama.
Even though i'm guessing you will still bump into liondani because chances are high you know him. haha
