Just reading the support forum and see that lots of folks from different boards (some are even admins) are getting this message when they try to post on their board:
"Error 1015 Ray ID: 3a88d88209030f21 • 2017-10-04 14:31:36 UTC
You are being rate limited
The owner of this website (www.tapatalk.com) has banned you temporarily from accessing this website."
It's a known bug and support has said that they ran a fix this afternoon.
