Detecting watermarked text is hard. Detecting AI garbage text is easy but then classfiying the garbage further is beyond us.

Maybe detecting watermarked text is a skill to be attained. Not allowing proper feedback and training will not allow people to notice the difference on time, thus ruining the data?

Best practice is to allow a number (scaled based on complexity of task) of training rounds (with short feedback loops) prior to letting people loose on the regular samples.
