If a person is acting as a Troll, and wishes to, how many times can they Vote Down your Hub? Do the Hub Administrators keep an eye on this? It seems with a few good Trolls, a Hubber can be ruined in ratings? Anyone...
Voting down has very little effect on your hubscore so don't get paranoid about it. A person can vote down your hub as many times as they want but it will only count once and will only have a short 24 hour effect (the same happens for voting up).
Voting up and down is only a small part of how hubscore is calculated and no other hubber has the power to ruin your ratings.
