To me it looks like an obvious AI response. The tone, or register, is completely off for a forum response (particularly one responding to a three year old post.
The user has only been posting for a few hours. One of their other two posts is equally unnatural in context:
I recommend checking the official Summerfest website, social media channels, or contacting the event organizers directly for the most accurate and up-to-date information on Summerfest 2023. Summerfest2023 date? - #4 by gregbowers
That “I recommend” jars – it’s too stilted for the context. And why would a human recommend checking the date of an event which finished six months ago?
I could be wrong, of course, in which case I apologise… but it looks like someone is using the forum to generate AI responses.
