If i happen to encounter such stuff, i just leave. And for stuff like moneycheat that would affect my savegame, DRG for example provides a couple of backupsaves to roll back. So i can easily avoid being affected by cheaters and if others want to cheat, i just don’t mind. But i would mind having to install a rootkit of questionable origin.
