You can't say that the whole space is toxic because you had bad experience with one member from bitcointalk forum.
There are a lot of people who are trying to scam people, or they are just trying to earn few sats in any way possible, and when they can get very angry if they don't get what they want.
My suggestion is to always check post history of any member in forum and think well before making some deal with anyone, no matter what his rank is.
I am going to tag member gondel and hope to see his explanation here.
