Splogs are blogs that are setup specifically for improving ones search engine placement. They often take the content from another blog and put it on theirs and try to get a link from the other blog by using the ping back system.
You maybe wondering what can be done about them? Well contact the provider that is hosting them, yes there are providers out there that care about splogs.
So in reading my normal blogs. I came across a post about someone that is having similar experiences that I am. Back in 1999 I signed up for classmates.com. Well Laura talks about another blogger that is having trouble getting unsubscribed. I recently put their sending IPs from even reaching my MTA. I tried and tried several times to get them to remove me from their list which was never done. Thought I was the only one having the problems.
Update 2008-06-25: I have now blocked all their sending IPs as it appears that I missed some.
Three law suits of note in the spam world, have had things happen, or have been filed.
These should prove to be interesting atleast the e360Insight ones.
I think they are just a little late with this one. This was an actual spam I received.
