Becasue some lists work for certain people and some don't, they can be useless to one but gold mine to another, depends on a million things. sponsor, mailer, proxies, quality, quantity...
Because some lists are mostly hotmail,yahoo,aol, and not everyone can get through to them.
Because some people have a great source for lists but don't know the first thing about spamming.
Because some people bought lists and it didn't convert for them and they thought they got screwd wile they actually got a very good list which will make alot of money in the right hands
many reasons, can't waste too much time on it....
must...... go....... mail...... something......
