So, I only know of one person that is being DV and that is coininstant which themarkymark has been downvoting for years now is that what you mean by:

also that isn't the point they also targeted people who I dont even know

?

He also has probably been DV'n a bunch on a blacklist that happen to be upvoting you is my guess

reputation falls significantly pass the threshold then my posts will be hidden for good

That would take a bit before that happens. Not sure DV you is showing they are afraid of public opinion or afraid of dissent. They are just sick of hearing about it is my guess ?

You realize Themarkymark isn't going anywhere and to be honest he has already won the battle. Why even bother fighting it ? Your rep will eventually go to zero and for what? so you can just waste time ? Just get back to doing what your doing who care about the DV's they aren't even that much.
