MRSPUTNIK bot net?

[incrediBILL]

This hit within a couple of minutes, worldwide IPs, all asked for the index page and then the about page. Very odd.

The UA has been in my ban list for yonks. If it hits, its IP is blocked.

I have a feeling it's a form-spammer but not sure on that. If it's that fast and that IP-variable it's probably a botnet.

But then: Hi, granny, here's another egg to suck! :)
