Another important point is that exposure therapy needs to be tailored to your particular level of discomfort. If you do too little it clearly won't have any effect, but on the other hand, if you go too hard it can make your anxiety or phobias worse.
Yeah, I signed up to see the progression. I presume that a ramp up may start off too easy for some people but will eventually start challenging without going overboard.
Exposure therapy is a proven technique for social anxiety and is the first line treatment. As long as the ramp up in exposure is gradual and doesn’t start off with “go to an extremely social event with a lot of complete strangers” on day one it shouldn’t be a problem and should be helpful for a lot of people.
I hope the program has disclaimers and warnings about when to seek professional help.
I feel for the original commenter, they seem to have traumatized themselves pretty badly, but I just don’t see how their experience maps onto this website at all.
