How long does follow block last?

I have had 5 accounts all follow blocked. I thought I would stop my bot, and wait a week before restarting, but my follows are all still blocked. Is this permanent?

There is no message when I try to follow someone - I can click the follow button, and it simply does nothing. No error messages or anything. Is this typical?

Lasts anywhere between a couple of days to even a month in some cases. Try to change your proxy and do minor actions of liking and commenting.
