Hi opwog,
Has this only been in the last few days (since Thursday 8/8)?
I ask because we've had to make some changes to our keyword filters and the rate limiter for posting to address the activity of some of our new friends who have wanted to spam us with offers of companionship overseas.
This message typically pops up in a few scenarios: 1) Your account has been idle and the system has logged you out (typical website security behavior) 2) You've hit one of the keyword interceptors and it's blocking you from posting 3) You tried to post a message to close to posting another message and the system is rate limiting you.
We found that for #3 that the more descriptive message we created that basically says "you're posting to fast, slow down" is not being displayed. We've sent that information over to the vendor for investigation.
