Where to flag low quality games that seem to be used for money laundering and other possible manipul

I know there was a thread called something like, "Are these games manipulating the cv" or something like that. But cant seem to find it.

Anyway, the point is i ran across 3 giveaways this morning for some shovelware i'd yet to see before. Sometimes there are some rather creative and inspiring titles for only a few dollars. But when they are $50, it's a red flag to me, and when all 3 are from the same user, doubly so.

These are better than ones i've come across, but $50 seems quite ridiculous.
