So my game (Drug Dealin Sim 2024) is a basic buy stock click to move than sell stock at a higher price type of game and not graphic at all.

It was my best game so far with  a few daily players. until I tagged it as "nsfw' which made it only show up if you are looking for porn games. I un tagged the game after realizing it was not doing as good, the game has never recovered. 

After I tag it as nsfw does it stay tagged as an adult game? because I am still getting nsfw clicks on the analytics page

mostly I am just curious how that works behind the scenes so I can avoid adding my games into the sexy ones. Is there a list of words/tags that will automatically add the game into adult?

and as for rule #5: No discussion of account restrictions: I am not aware of if it has been moderated by an admin just to be clear

On itch.io, the rule of thumb is: if your were at work in the office, or at home with family (maybe older, conservative people), and someone saw you looking at the game page, would you get into trouble? would you have to explain yourself? Then the game is probably NSFW, otherwise no. Hope this helps.
