It seems to be always the same spammer, at least in my part of gnutella net, and I have checked and compared often, at least 50 times in two months.

The IP-Adress is always 194.213.194.37, as far as I can see, which resolves to:

inetnum: 194.213.194.0-194.213.194.63
netname: GTS-CZ-HOSTING2-PPAHA
descr:Server Hosting(Praha) GTS Czech a.s.,
possibly a dial-up.

I am not sure if it would be helpful or effective in any way to complain at his isp (above).

I wonder how many spammers are out there...
