Man they don't educate the mods enough around here ever hear of cheat breaker? It's a client side anti cheat which could probably do more than look around the versions folder or mods folder, granted it probably isn't set up for internet connectivity or whatnot, however with modifications to this (or just make a whole new CC version) every CubeCrafters would have to use the client to play on the server, may make the server lose popularity but if it comes down to it ;eye roll; then it may happen, the only question then is legality and spoofers, hacked clients could send the server false packages telling said server that the client is the proper version, legality should probably be fine, some screen shares (on primarily hcf servers) have people looking through their email so if put in the terms and conditions of the server it should be fine, but this is all probably entirely unnecary for cubecraft, it's only really good for closet cheaters anyhow.
