I chose no - just ignore the idiots for a few reasons.

Any voting system is broken because there are bound to be people that mess around with it.
But I've found it to be helpful in weeding out a few constructive criticisms once in a while.
Basically it all boils down to what people think, and people have various tastes. For my own personal use I can see why I didn't get a full score on one picture or a full score on another picture and try to learn from that. This hobby is not like that for everybody out there, but I actually try and improve my shots one by one - but again I tend to have some fun a long the way and post shots I like and know will fall into taste with some but be abhorred with others (but I think its fun and might give some inspiration to other ideas or pictures).

My 2 cents
