My stats support that, several use multiple accounts to down vote everything that I write. Twice they harassed the man that I borrowed my sign-on name from. He still loves my memes and told me to send them out to his pasture and he would be glad to talk to them. My money is on them ending up on a milk carton, he is a scary dude.
The stats do not bother me, I rarely check them, I limit my responses to people that actually want to discuss things and just block the trolls that are just here to insult others. I also have a short list of people that make memes that I respond to, you are on the list, I follow you and about 20 others. For a short while I could discuss events with one of the left mods but that went south when the insults were used instead of an actual discussion. So, I make memes, head to work and check back later to see if someone responded.
