Over the last 2 days, I've seen on my blog an influx of spam comments, some more spammy than others but all spun, with the URL pointing to a facebook profile. The facebook profiles are personal profiles, not pages, and have no links on them. Here's a couple of real examples: /profile.php?id=100003406025551&sk=wall /ion.ava.1?sk=info Does anyone have any idea what it's all about and how it works? The only thing I can think of right now is perhaps they want you to add them and then they'll try and sell you something, scam you etc whilst pretending to be a friend but that seems a bit farfetched and I assume it's more SEO, but I can't imagine how. Any ideas?
