Hence the ToS and the clarifying post from the enforcement team that is pinned at the very top of the forums.
Look FC isn’t the first game company to put rules of playing their game on their servers not within the game and instead have links to webpages…that’s pretty standard in most games so I’m not sure where you are going with this outside of saying the entire industry is being unfair to those that don’t know to follow the links and read the rules.
I mean defining what is memory hogging is a bit problematic and you can have a case there but I have had clues lots of times if I gotten carried away (rubberbanding always in the same locations, doors not opening, sound and actions no longer in sync etc) . When these things happen. I redesign and rebuild.
