I think it depends on what you mean by spamming. If you mean getting a bunch of bad messages from people, guys typically don't have that problem. A lot of girls on dating sites do though, which is one of the biggest ways they are broken. However, I've personally started to notice a lot of fake profiles on OkCupid. I know they're fake because I keep seeing the same pictures of girls with different written profiles or the same profile description (word for word) on profiles with different pictures. In my mind, this is a form of spam too, and it could get to be a problem that OkCupid needs to solve.
