Twitter Problems Please Help

I have 20 twitter accounts

5 AC accounts

I have 4 twitter accounts for each AC account

Im using twitterfeed to automatically post my AC updated to the appropriate twitter accounts

Im using hummingbird to follow/unfollow - I follow about 200-250 people daily on each twitter account

I wake up this morning and every single one of my twitter accounts is banned...

What am I doing wrong, and how can I prevent it from happening again

did you set up all of the accounts on the ip address?

if you did then if twitter see one account as a bit spammy or somthing then they will ban that account and ever account under that same ip address.. you can email them and ask them why they banned you and then ask them to give you your accounts back
