I apologize in advance if this seems like whining. I have, however, observed someone - I think - systematically downvoting each new answer I provide. It would seem to me that this sort of downvoting avoids being reversed (as a recent spate of downvotes I received did get reversed) and is thus slightly frustrating. That said, I am aware that a) maybe my answers simply stink and deserve the downvotes, and b) the down votes don't really matter in the big picture. I agree, but still, I can't help but think that I am unfairly being targeted. Is the SE system able to detect such behavior?
