Yes, they are exceptionally annoying; they are part of a greater downvote "bot farm." There's a really good explanation on @pirateofthedtube's site:
and the latest news now is that Steemit, Inc. is onboard with the problem and are removing the 15SP "automatic delegation" that comes with new accounts... which means these downvote bots are now completely "toothless."
But still annoying!
