Howdy folks!

I was submitting my site to a load of search engines using's Submit Free service. I've used this before and it's gotten me listed in a fair few directories.

The thing is, for some reason Lycos threw up this error:

We were unable to spider your page.

error: Lycos Error: excluded by robots.txt
All the other submissions to other sites worked fine, and the last time I submitted another site to Lycos it was OK. What's going on?
