I think the only way SE could really and effectively combat it is if they added anticheat software. However, doing this itself presents a lot of problems - the main parser people use would get hit. Modders would probably get hit. And so on. Basically what's currently the big DADT grey area would become a black area, and that'd make a lot of people very angry and SE would lose a lot of their playerbase if they didn't manage to find a way to allow those things or a replacement.
