Spam Pings

I've had a flood of spammy pings on one specific post. I've disabled ping backs on that post and will continue to disable pingbacks when I see spammish "abuse" of the concept. I'd certainly rather not do this. One of the values of a pingback is if someone actually writes a RELEVANT article and cites another as reference. If it looks like someone is just attempting to place an add for their services in a comment/pingback, that comment/pingback will be deleted. If that post becomes a nuisance to me to maintain, my solution will be to cut off comments/pingbacks. I suggest if you're looking at ways to advertise your site, you might look at Google Adwords.
