I've looked at the bot threads at WmW but didn't find much.
I have two, of what I take are bots, tag teaming Wordpress.
One claims to be from Cambridge Mass., MIT
The other just US.
Both are checking ever tag, category. And some posts and pages. They might be working together.
Anyone heard of MIT having a bot?
They certainly have a lot of research on crawling the web, most of it from back in the 20th century.
