Fact is just
1) This post is useless cause its no official twitter account
2) As long you get no mail with "your banned" you are not.
Just wait, i have 3 botaccounts who do exatly the same, 1 is currently not able to log in and 2 have no problems, all on same ip
for me it looks like the problem is on a timeperiod created accounts also some buddys told me just hte accounts they created before ~1 month are currently not able to login
