i know alot of people make "spam" made for adsense sites.
Personally I dont see a point as they are very short lived and likely to be banned by google.

Just my opinion of course

Its true, its a waste of time most of the time. Some people automate it though.
But it really clutters the web. Personally i prefer to make a big quality site rather than small spammy ones.

Yes but those ppl making spam sites DO make good money, well some of them.
Making a big site is HARD work though, alot of people dont want to put the effort in.

Nothing wrong with doing that if it works. If i could make money like that i would do it in a flash.
Who cares if its not long term?

They care if they get banned by adsense or something. there goes their income.
Its too risky now, google are not afraid to ban people anymore.
