That's very unfortunate, since I believe that Yahoo! is responsive to complaints about GeoCities-hosted spam sites.
You're not the first to say that but, that too, is very unfortunate since IIRC back in the days of prehistory SpamCop's philosophy was exactly the opposite: that reporting a compromised system after it has been hijacked to relay spam was too late, not to mention a neverending battle to exhaust a practically infinite resource. The real value was in taking down the spammer's web sites, interfering with their revenue. In some cases this is no longer true due to 'bulletproof' spam hosting but, where it's likely or even possible that the spammer may be shut down and may have to move on, I'll take a moment to contribute to that.
You are not the first person to say that, either, and you may well be correct but if everyone in history had just decided to accept what was there or forget about it in stead of trying to help and improve things, we'd be living in a pretty crappy world. None of us would be here if Julian had ever accepted that e-mail was e-mail, like it or leave it. Maybe nothing that I will ever do will result in significant improvement, but I refuse to sit back and not try.
I do like SpamCop, and shame on all you "like it or leave it" people for failing to recognize others' efforts to try to improve a good thing.
On a more positive note, I see lots of info on how to contact JT, the deputies, and other fine folk who, unfortunately, have no control over the reporting mechanism. Does anyone have contact information for 'the powers that be'?
Thanks to all who contribute, in whatever capacity.
