Yes, but I also think it will be trivially by-passable if you pass your output through another LLM. At least for text.

It might help catch students cheating, but not real spam-bot usage. As soon as platforms start checking for watermarks spambots will add anti-watermark passes.

I read through their earlier announcement, i don’t think it’ll be trivially by-passable without distorting the original message.

I would agree it may not help spam-bot usage, however at this case seemingly the only user detection is likely an id/badge check, which is not good.
