So THAT'S what they are! Here is a link to my Google search results:
"Fake Blogs Sploggers"
I got some requests for these kind of generic blogs to be added to my sidebar list. They added mine to theirs, so I reciprocated, at first.
But then I started getting more and more requests. All the blogs seemed to have a kind of generic sameness, often using the same template, and their posts seemed rather generic and impersonal. The requests to be added to my blog roll seemed odd, unnatural, like they could be computer generated.
That's when googled "fake blogs" and found out about "sploggs".
I made the mistake of adding some to my sidebar, and now I'm being spammed by hundreds of them. My spam filter it catching them, but it's inconvenient to deal with, and creepy. I may have to turn off comments on my blog for a while.
I've deleted suspected sploggs from my sidebar. I'm not accepting new reciprocal links anymore, I'm sticking with people I actually know from the past. I may even delete some of my blogrolls, as they don't seem to work half the time anyway.
Things like this dampen my enthusiasm for blogging. It's like dealing with Pod People. I've definitely got better things to do with my time.
