For Self Moderation, I would say that at the time we are living in, people do not believe a good change, infact people nowadays do not welcomes the change, so they accuse every hard to understand and difficult to believe platform as a scam.
A platform like us never built in just several days, it took efforts, explanations, hardwork, faced criticism and never giving up attitude.
So, we cannot tolerate a negative or false accusations just because of the lack of approach to know us what we are, we kept it self moderated.
