I keep seeing a pattern here so I thought a new thread was warranted. It seems that for the most part, people that get banned are guilty of overbuilding for a particular niche/merchant. I've seen multiple stories where someone has built 200 or more domains/sites for a single merchant, all with the same keyword list.

Now, common sense tells us that this is not going to go unnoticed.

Not only are you taking up multiple first page listings in the serps, but you are likely pissing off other web masters and the merchants themselves. They report the sites, then you get hand reviewed and all of your domains are gone. Common sense and self control
