Twitter instant banning accounts

Does anyone else have an issue with twitter disabling accounts? I've been using tweetattacks for a few months now, and just recently since I changed proxies to another provider (not sure if this is the reason or not), but after one post it says "The remote server returned an error (401) Unauthorized". I tried changing up the text, and made new urls from another shortener service. Neither one of those helped. As soon as I post a link the account is instantly locked.

Has anyone else had an issue like this?

The new proxies you got could have already of been banned by twitter.

That's what I was worried about. I wasn't sure though because they all log in fine, it's just after one post is when they die. Thanks for the assist with that. :\

try 1 account manually, set it up fully, add a few tweets and follw 10 people, come back the next day and see if its still active. Perhaps Twitter is picking up TA?
