Fun experiment.
Glad you asked!! The answer is a lot of them. Here's a highlight of the few that make me the most angry:
- only 250 roles in a server / created per guild every 24 hours
- only 500 channels in a server, period
- only 5 channel renames / topic sets per 20 minutes
- only 50 channels per channel category
These limits have had far reaching effects on the structure and implementation of ctfbot, which only barely works around these.
