I had a visit this evening from OVH (167.114.156.nnn) with this:
Domain Re-Animator Bot (http://domainreanimator.com) - support@domainreanimator.com
which sounds a bit scary.
A quick look at the website is as horrifying as it sounds.
It requested 1015 pages in 25 minutes.
Robots.txt? What's that again?
Stuff of nightmares.
Fortunately my pet monster swallowed it whole.
