It will be interesting to see when spiteful users start creating LLM powered bots that are designed to waste reddit moderator's time in such a way that the moderator's reaction doesn't rise to the level of a ban, but enough that it consumes a disproportionate amount of their time.

It'll be a fabulous display of malicious compliance where they're doing something somewhat similar to your suggestion of using chatgpt to rewrite their messages, but with an entirely different outcome than you intended.
