Don't know how to do quotes here but:
"Any community always ends up attracting downvotes and trolls, and the conventional resources such as the suicide hotline chat are only meant to keep you talking and don't help discuss chronic problems."
This is pretty much it right here. It boils down to qualifications, money, and the anonymous nature of the internet. It's hard to give real and useful advice to someone based off of only a couple of internet posts.
Offline, are you gonna run into shitty therapists who deserve to have their license revoked? Yes absolutely. But the people who can help have qualifications and charge a lot of money for their time. They're not gonna come on the internet and dispense useless or generic advice to strangers. It would be a waste of everyone's time, not to mention the whole issue with separating work from life.
