I’m sorry you had a bad experience, but personally I’ve never understood “microblogging” myself. Like on Lemmy/Reddit, you can have pointless short conversations with people. On BlueSky/X, what is the point? It just seems like people screaming into the void hoping to attract some likes. I never understood how you were supposed to use it. Part of your problem with it seems to be that you want it to be more of a forum when it really isn’t.
Anecdotally, I have seen a case of “stem cells tourism” where the patient traveled to a foreign country to get stem cells injected into their spine. Can’t remember why they paid for this treatment. When they came back to their home country they started developing multiple spinal tumors due to the injections…causing significant morbidity. It honestly sounded like a horrifying case. Apparently this is not unheard of. I work in healthcare, but do not have a direct patient care facing role, so unfortunately I do not know what ended up happening to the patient.
