I doubt you will get an answer. Unless they need something from you, to close the investigation.

Look at it from Itch's perspective. Something triggered their defenses. Worst case, your account and mail were hacked and are now spreading viruses. That your development computer is infected and you uploaded infected apps is actually one of the many theoretical scenarios.

From observation I can speculate that the automatics sensitivity was increased. There is malware uploaded to Itch every day. And they have a hard time removing actual malware that was reported as such. I could point you to a dozen such malware projects.

You are using renpy and some versions of renpy trigger false positives.

Oh, and all your games have a pricing and or category problem. They could have been reported as scam for that.

Your games are pay what you want, but have no game to download at price 0. That is false advertising. You are misrepresenting the price of the games.

You seem to have individually priced files at $ 6 on all the games. How is this calculated in a bundle? I do not know. The faq has no information about bundle prices and discounts in regard to individually priced files. Is the $ 16 bundle price applied to all the games or is it split over all the games? Can your customers download all the games at the tier of $ 16 or at the tier of $ 1.06? Individually priced files can only be accessed, if the price paid satisfies the minimum price of the file. 

For project ownership in library this does not matter. You can always access all paid files in a project, even if the price changes. But your projects have no paid files. They are individually priced.

For that matter, I dot even know what happens with individually priced files, if you buy on a discount. Or a discounted bundle for that matter.
