Advertisers and Spammers

I came back from a long vacation with hubby--our first in 5 years--and find spammers on my blog. Go figure. Does that mean I've "made it"? They've cropped up before now and again, but this one found an old post and spammed. And to a completely unrelated site. It has nothing to do with anything I've ever blogged about.

So, I deleted it and will continue to do so. How annoying! It's bad enough my facebook account is spammed out, but my blog too?

How do you all handle it? Do you just delete or have some of you turned on the "approve by owner" feature? And does it work?
