I'm with you Opti

Live and Let Live.
I used to report people for spam, scanning for trojans, spamming sponsors via email..... but what is the point of wasting time doing that. The sysadmins I have come across do not give a monkey's unless their servers are at risk. You are likely to be accidentally placed on a spammers list by someone not reading the headers correctly and entering your details instead of the spammers.
There is a major British ISP who serve millions of customers and their total abuse department consists of 4 people. They have no cat in hell's chance of dealing with minor cases of spam.
On a larger scale, Google are powerless to deal with a lot of shit which goes on with their serps. If you report something spammy what's the worst they can do? Ban a domain? Ban an IP range? Adjust their algo?
The main problem with 21st Century web communication is the fact that webmasters, spammers and hackers work around the clock, whereas sysadmins and company employees work 9 to 5.
