I don't know you but I'll just say something: Dry up that pesky liquid from your eyeballs. I'm pretty much nobody on this site, so I've never been trolled. I'm like a fungus growing in the corner of the party room, no one bothers to mess with the fungus, everyone's busy partying with the pretty people. But I imagine I'd feel terrible if the same happened to me, that after all that effort you lose the result.
However, look at the positive side! Feel flattered! Do you know how much time all that rating down must've taken? How many points? How many accounts that person might've made to achieve it, and therefore how many email accounts all they account creating must've taken? A LOT. Now, why would someone do that? JEALOUSY. That's how jealous they are. Just think, how sad and pitiful a person must be to be so immature.
If I were you, I'd go frolic on a meadow or something, I'd be that flattered.
I donated my seven points to you, because I felt bad. Didn't do much but it's something.
