Can i use automated tools detrimental to MSN rankings?

[isismedia]

I checked my site after a week or so. It says not listed in MSN. I am listed. The site dropped back a couple of pages. They were quite solid since I had these positions for a year. I am assuming MSN did not allow the tool from checking. It must have banned the tool. So it appears as if it is gone.

However, my site dropped. I don’t know what to make of it. Is it a coincidence? I am not sure. I believe MSN stated that they were cracking down on automated attempts at data or something similar to it. Is this the result of that? Any dope on this?

By the way, I only checked the keywords. My other websites haven’t been affected.
