Dual error: denied due to update limits and Text contains malware



we’re getting errors when sending messages. But these errors contain multiple explanations:

403:The request is understood, but it has been refused. An accompanying error message will explain why. This code is used when requests are being denied due to update limits (https://support.twitter.com/articles/15364-about-twitter-limits-update-api-dm-and-following).
message - There was an error sending your message: Text contains malware: Kun jij een euro missen??? Namens Spieren voor Spieren bedankt. Help mee en steun deze actie: http://bit.ly/16skZSq.
code - 151

What is the real problem here?
1 Are we hitting a limit?
2 If our text contains malware (which we can assure you is not the case) , what part of the text is considered malware, is it the url or the actual text?

Hope someone can help clarify this ambiguous message.



The malware message usually occurs when the system suspects the URL is abusive in some way – https://support.twitter.com/forms/spam can help you get that resolved if that message is in error.

It’s also possible you’re hitting update limits. Are you monitoring/throttling how many tweets are being sent by this account?
