That's going to happen no matter what you do when you have random people involved. Just accept the fact that there will always be bad players and some can't be helped. If you are going to take raiding seriously, then you wouldn't be using the DF for them. Even in a multiplayer game, I don't need to be treated like a baby that can't think for himself. If I need help, then I have so many choices to pick from. It's not the end of the world if you suffer a wipe every now and then.
