Link Development Forum

For instance it can make a url like this:
http://www.example.com/forum/showthread.php?p=6314419#post6314419

look neat like this:

In my opinion, it doesn't do much for seo any longer as Google has adapted since the day when mod rewrite was a big thing.

mysite.org/page.php?=

The tag along comes after the '='

so, it's;

mysite.org/page.php?=othersite.com/page.htm

It looks just like what a linked back affilate (link) would look like, but on this particular site, there are no affiliates.

Just started showing up around the first part of November, and struck me as quite odd.

Could it be some kind of referal spam that I'm not aware of?

The site is pretty new, 1-2 years, and though we have sites that are much older, 6-7 years, this is the only one these odd url's have shown up on.
