Well, this whole thing smells rotten to me...
the thought that you could start a niche specific site, do well with it, start another niche specific site, then some more, and then get penalized for it is... well... quite frankly stupid.
If I wanted hockey skates and a new graphite stick, then I would much prefer to see niche hockey equipment sites than a large "sports" site.
One other question: Are you possibly using the same google pay account for all the sites (assuming you take google pay / google checkout / whatever it is called)?
