Just recently I have seen reputation added back from serial down votes, but I have also seen reputation taken.
Is there a way to check if you are being serial down voted by the same group of people? If the same 3 people down votes every so so question you have can they get you banned or suspended?
Update: I have noticed when you edit in a short period of time reviewers tend to be the same people and are more likely to down vote. Many of my down votes could be coming from that since I do edit often? Reviewers on some sites could just be the down voter type?
Is there any way to check to see if someone is down-voting you but with time restraint or with strategy not to be flagged and reek havoc on another account? Can someone down vote all of a user's posts over time and not be flagged?
