Blimee...
Logging the IPs and working with ISPs to inform the end user...
Impressive if it works... I tried that once. I was getting several thousand emails from one IP every day. I contacted the ISP and it stopped. I was impressed. A month later it started again. Same IP, so the user had obviously learnt very little. I contacted the ISP again, nothing happened, the spam continued.
The IP is still blocked on my email server. Glad it was fixed and not dynamic!
I think MS should be made to force an update onto PCs which works like the browser choice app, but gives a choice of antivirus.
It's amazing to think how close the music industry have got (or are getting) to getting laws introduced which can have you disconnected from the internet, yet infected PCs which cause problems for far more people are just left to spew their infections penis and enlargement emails unchecked.
I'm sure if they introduced a 3 strikes and you're off the net until you complete a PC driving licence course would be far more widely supported.
Oh damn, I hope I haven't just given HMgovt a way to spin the music industries plans onto us under the guise of internet health.
