Don't Twitter frown on auto-following? To the extent of banning developers who implement it, I thought.

Not unless it's abused. I've capped the maximum amount of accounts one is able to follow at 1000 a day. Same story for favoriting tweets.

Well, in that case, carry on with all good speed, stout yeoman!

Will do. Do you use Twitter at all?

I do, I do, but at a very low level.
