Back in the day on various forums I saw people try to make them happen. Not sure how successful it all was. None of them were anything like a legit well funded summer camp. I think they all ended up being weekends or extended weekend meetups with lots of eating.
In Mauritania, Africa, young women go to camp like these. But it's most often against there will and is a human rights issue.
For a legit "fat camp/feedee camp" that is something funded and structured like a summer camp where people can go and have medical professionals assist with gaining weight as fast and healthily as possible most likely doesn't exist and would take a lot of money, people, and resources to make happen. I could be wrong. Maybe there is something close to that. But I've yet to see it. Sounds fun tho! Lol
