Yahoo Spiders won't leave

[rookiecrd1]

I have about 100-200 yahoo spiders who have bene constantly as 3 of my sites for the last 4-5 days. Is this normal? Should I just allow them to do their job? These are all forum sites.

I am seeing the same, also a forum.

Normally, the bots come heavy once every two weeks. They come all at once, like a DOS attack, 500-600 of them for about two hours, each hiting 15-20 pages a minute.

But this is different. They came a few days ago, about 100-150 of them and are hiting the site much slower.

It can only be a good thing.
