Yeah, the same thing happened to me when I reported an itch.io url recently.  Plus, on a previous report that I sent in (that was resolved) they never sent a reply back about the report with a quick summary of what the end results were.  Itch.io's system really needs to blacklist offending urls since users that were blocked before can re-use the exact same url, html page, pictures and (I'm presuming) game files.  Itch.io users should only need to report on a url once and once it's justifiably removed from the itch.io website, the same url, html page, pictures, game files, user email, user name, and whatever else info the offending user provides can't be used again on that same url since the website system will block it.  The offending user's account probably needs to be nuked as well.  I'm not a lawyer or anything but itch.io's hosting of software and what have you that an itch.io user doesn't actually own might open the site up to possible lawsuits since it might be considered they're aiding and abetting in the illegal selling of those items.  In a similar related topic, when I see a listing of a known game that wasn't available online digitally before, I really have no idea if it's really an official website by the creator of the game or not.  When I see stuff like that I almost want to report it!  And not to sound mercenary or anything but it might be reasonable for itch.io to provide some sort of reward for accurate reports from users.  They're performing a task that the website really ought to be doing so it's only fair if you ask me.  Or it could be something as minor as keeping track of how many bounties have been collected by the user like some sort of Steam acheivement.  Another idea I thought of related to this is that the itch.io user doing the reporting could use a "withdrawl report" option in their account since I could've used that feature on another report I made recently since I came across additional information via the net that the game I was reporting should be legit according to a reliable source.  If there is currently an option to do this on a user's account I didn't see it.  Also having a text field like this one to provide the reason for the report's withdrawl by the user would be needed too.  And on the flip side some sort of controls need to be in place on the reportees if too many false positives are reported (though you guys might already have stuff like that in place already).

I guess I need to post the confirmation ID's here too?  The report that's still outstanding for me is this one:
R-11873

The other report I'd like to withdraw for the time being is this one:
R-11910

Or for the latter would I just need to send a reply to the e-mail that postmaster@itch.io sent me?
