Dealing with Scum Bus Drives

[Mr. Flay]

What should a Moderator do when he designs a Bus Drive role for a Scum Group and then they start changing the actions every night.
Should he inform the townspeople about possible changes if they targets are changed or not?
I'm really confused about this, just want to know what is the best thing for a Moderator to do.

For roles that normally do not get any response to their actions (eg, doctor), then they should not be informed.

For roles that do normally get a response (eg, cop), you have two choices:
1) You can tell them their new target (cop investigates X, you give them the report "Y is innocent")
2) You can not tell them their new target (cop investigates X, you give them the report "Innocent")

Frankly, I consider 2) to be bastard modding.

As do I.

I hate the Bus Driver role, intensely.

[Mr. Flay]

I think Bus Driver is a rare enough role AND a powerful enough role to tell that it exists, IF a Cop happens to be the target. Besides, it's still going to be damnably hard to get rid of even once Town figures out it's there.
