The discord plugin tries to fetch history from from channels and goes over the rate limits.
Which triggers a temporary ban:
You are being blocked from accessing our API temporarily due to exceeding our rate limits frequently. Please read our docs at Discord Developer Portal to prevent this moving forward.
Cannot do anything on the native client. Messages don’t show. Pidgin still receives messages but cannot send. I am cut off from the only way from communicating with 95% of my contacts.
Several issues have already opened on github (the first one over 6 years ago).
The workaround is to disable “Fetch unread messages when account connects” altogether but that leads to loss of all offline direct messages.
