I saw this on Engadget – Twitter ‘rate limit’ messages are due to an error, not your bad tweets – Engadget: https://www.engadget.com/twitter-rate-limit-exceeded-002326145.html.
Thought this was an unusual Weirdness Wednesdays choice for this week. I don’t use any of the apps or other systems to tweet. I don’t tweet much, other than those tweeted when I post. Hopefully, it will be fixed soon for those experiencing problems.
The service is having an internal backend problem.
