General logging was in the specific list of problems. Servers you're not in control of were an explicit part of point number 1.
Bots can possibly solve the issue of "I need to get logs of arbitrary channels I'm in", but discord in particular makes it difficult in a way that IRC does not.
Discord is in some ways much worse than IRC for logging.
It's also better in some ways. But there are important differences in each direction.
Discord could largely solve this with a ToS change. But until that happens, it's a problem.
