Non Gold Member Bumps

I may delete a dozen or more bumps a day. They are handled if we see them but we don't necessarily babysit every sale thread. I look for patterns, if I find one I will look for others from the same member (and usually find more bumps). Along with that comes a message or PM telling the member that bumps are not allowed.
I've noticed a lot of non gold members bumping their for sale ads. Do they get gold benefits now?
