The OP account definitely seems to be.

All the posts they’ve made have a header, sub header, “::”, and description, with all the copy around the same length each time. It’d be a weird amount of effort to not be using GPT for this

Yeah but they keep removing stuff and locking down how useful it can be. First they took GPT4 and put it behind a paywall, now I have a limit to how much I can use it per day and have to switch between multiple accounts sometimes. Makes it a lot harder to work it into new projects knowing I might have to wait on GPT to get its shit together every other day
