How many follow/unfollow on Twitter per day using buzzom ?

I was hitting buzzom the other hard, 1k +plus unfollow/follow and got the a account suspended.

What is the magic number to stay under with Twitter to keep the accounts active?

 

I've heard its about 500 for new accounts

 

Once you get over the 2k followers mark, does it stay the same or can you increase the number of following each day.

 

I think the daily unfollow/follow limit combined total is 1000 if you have 2000+ followers.

 

cool, what is it below 2k? What is a limit to stay under until you get to 2k?
