I've noticed a larger number of "likes" coming from spammer sites - people who post those opinions so that others track back to their home site. I like "likes" from (ahem) like-minded folks who are truly interested in the content. But these spam likes that link back to money making schemes or worse are annoying. And possibly harmful.
I would prefer to leave "likes" on for legitimate users, but kill the spammy ones manually as I notice them. Even better would be linking the "likes" system to a spam-fighting utility, much as comments are handled now.
So how about it. Do you like "likes?" Do you see them as a valuable feature worth preserving? Or should it just be turned off or killed entirely to spare everyone the nuisance?
The blog I need help with is string-or-nothing.com.
