There is a thin line between exploit trawling and data gathering and I suspect the later is to blame.
By seeing if certain pages exist on your site Slurp is gathering data about what your site is made of, which obviously affects your rankings (or they wouldn't waste resources).
Some of those look like tests to see if your site throws 404 on never existed pages as it should instead of say 301 or 410. Some of those look like they're testing for slurp only doorway pages.
It's not all bad, in fact Slurp wants to know if you have a video player, a top content section, an about page and a company page. Obviously Slurp places value on these things so jump on that free search crawler insight and create them!
Thanks for sharing the list - it looks like Slurp has figured out your site is about sports and wants to know if you feature yahoo.sports and/or getty content... since authority sites likely would mention those two sites perhaps you should too. On the other hand Slurp may be looking to penalize use of those resources... hard to tell. now i'm off to see what Google's been 404'ing on my site.
