Did it ever occur to you that maybe people just want to play with your builds? I myself go onto servers and save the builds so I can load them later and have fun. Unless you're hosting a 24 hour dedicated server for every single one of your builds, there is no other way for people to experience them other than saving them and loading on their own servers. People save your builds because they like them and wish to play with them after you go offline. God forbid people have fun when you're not present.
Sure, there's the odd 12 year old jerk who will claim that he built it himself - but that's just some dumb kid on the internet. If you post your builds on the forum (with the save file would be great) - then everyone who matters will know that you built it.
Because you people still don't understand this, I now have to waste a huge amount of time making it impossible to disable event saving in v9. Thanks.
