"My vibecoded stuff is indistinguishable from handwritten stuff" and "I got anti-AI comments after vibecoding my website even though I didn't say anything about AI" are not very compatible with each other.
There was absolutely nothing showing that it was vibe coded other than the fact that a website that didn't get any updates for 5 years suddenly got a 20+ bullet point update. People just assumed it was vibed because of the sheer number of changes.
There was not 1 mention about anything being broken, they were simply complaining about AI.
