Since approximately 0900 PDT today, we at @trueanthem have been seeing and increasing number of error messages reading “(185) User is over daily status update limit.” when attempting to make Tweets on behalf of our customers. Currently we have received this message 3,235 times today. This is causing scheduled tweets on our service to fail as a result. Based on the information provided on this page (https://help.twitter.com/en/rules-and-policies/twitter-limits), we should be able to make 2,400 tweets per day per network account, and nearly all of our affected accounts tweeted fewer than 100/day over the past 24 hours.
We have not previously encountered this issue before and believe this is bug unless you can point to some documentation regarding a change to daily status limits. Can you provide us with any insight at this time?
