Tell me how much money you earn for such entries, does the exchange pay you?

I want to warn people about this exchange, I see people have problems with withdrawing coins from this exchange. On the discord channel moderators block, give ban to people who write the truth and report problems with payment.
The information received from the moderator shows that the exchange is decentralized
I will ask the question if the system is decentralized, can the withdrawal of coins be blocked? Why is the exchange cheating people and saying that it is decentralized?
