Or maybe it’s just strange classification. I see a lot of prompts on the internet looking like “act as a senior xxx expert with over 15 years of industry experience and answer the following: [insert simple question]”
I hope those are not classified as “roleplaying” the “roleplay” here is just a trick to get better answer from the model, often in a professional setting that has nothing to do with creative writing of NSFW stuff
I strongly bet that this is it.
