Problem with Twitter, cannot autopost due to "request looks like automated"

Hello,

I have this error with autopost on Twitter since the last couple of days:
[Error] [Twitter – Twitter] – -=ERROR=- Array ( [pgID] => [isPosted] => 0 [pDate] => 2014-02-11 19:03:07 [Error] => Resp: {“errors”:[{“code”:226,”message”:”This request looks like it might be automated. To protect our users from spam and other malicious activity, we can’t complete this action right now. Please try again later.”}]}| Error: | MSG: Wooden pallet table : https://bit.ly/1gqkMzr – #PalletTable ) | PostID: 8782 – Wooden pallet table |im

Is this due to a change in Twitter API or is it on my side ? I have the last version of the plugin.
Thanks for your feedback!
