Another Technique

It's been a while since an update here... why?, well because firstly I've been very busy with work that pays the bills and secondly everything's working great with the tar pit. I have come across another technique for reducing spam which I may try and take a look at real soon:

It works on similar principles to the tar pit in it exploits badly written/implemented mail servers. Will post more info if I find it to be useful.
