Someone asked this before, Chainsaws answer was basically the game isn't for money so if a site is going to use it, its not a real bother. (Edit: I just looked at the site and they technically credit Chainsaw lol but the comments seem to feel positive about the game... ones a little strange tho I won't repeat it here but if one were to check they can see what I mean. Also now I'm curious how many plays/visits the game has gotten on itch since porngameshub claims 87k visits. I've never really trusted the numbers on those sites even on the more credible ones like gamcore)

I forget exactly how, but there's a way you can look at a site's web code, and usually you can find random number generation code on such things. Most commonly on shopping sites that tell you how many people are 'looking' at an item to try and pressure you into buying it. The vast majority of the time, the number is just spat out by a random number generator.
