This site gives some interesting DV stats. It's some of the biggest accounts they get the most. I think that's partly down to long-running feuds between old/big accounts.

We do see a lot of new accounts set up to try and exploit Hive with plagiarised content and other schemes, so those are likely to get DVs as soon as they are spotted. People can track who is voting them up and they may have scripts to 'follow the money'. You need some reasonable HP to earn that way and it can be tracked.

I just hate to see people put off when they attract DVs through actual ignorance of what is acceptable.
