What are these?

[airframe doctor]

Just been looking at the online users & noticed several of these....
MSNBot Spider, GoogleSpider & Yahoo Slurp Spider

Can anyone shed light on to what these are???:PDT_Xtremez_35:

They are harmless.

Basically its spidering the forums. When people use search engines like MSN/Yahoo/Google for a certain topic, say for RAF chat as this forum is about, the forum will be in the search list hence increasing traffic and possible new members.

Sometime ago we had a thread with "Free" in the title, that we had to change as anyone who had "Free" in a search engine would eventually b directed to this site...In itself OK, except most of them had been looking for free sex!

As MM says, they areharmless, and for some an intro to The Goat!
