My site has an auto-stop, block, report system; most effective for stopping script kiddies operating abusive bots. For a number of weeks now, the MSNBot has been caught in it's net. Finally, I've got sick of it, and am also reporting it here:

The ASN for each IP above is AS8075 [cidr-report.org] (MICROSOFT). Each event above has been auto-reported daily to the relevant abuse email address; naturally, no action. Each link above shows the relevant abusive activity from that IP.
Each IP caught in abusive activity gets banned from my site for a week, with a notice explaining why. At the moment, at the end of that week the MSNBot IP takes up it's abusive behaviour all over again, gets stopped by the Stop-Abuse routines, reported & banned.
This abusive behaviour first began on June 20 this year and was reported in this forum [webmasterworld.com]. It continued until July [webmasterworld.com] then, thanks to a WebmasterWorld member with MS contacts, it stopped. All was then quiet until a month or so back, when it started all over again.
For the record, the odd Google IP & Yahoo! IP has occasionally got caught up in this net. However, nothing like the extent of MSNBot IPs, which I think can now be classified as endemic abuse.
