Bernie, would you downvote her if she wouldn't use voting services?
I can't see the amount of contribution being determined if someone is upvoting their posts or not? I've found bought upvotes unrewarding on a personal level and on a long run, I can see the harm they are doing on the service.
However I'm worried if some will see your acts on paid upvotes as personal attacks on the users themselves.
I can see this can be seen as more offensive than it would need to be.
