And after the platform stopped paying, I lost both access and interest. Only this account remains. But there the voice was probably 5 if I'm not mistaken. But although when I just signed up for curatorship, I earned 6.74 dollars a week later, and not a cent here

Please do not mislead yourself or others. The platform has not stopped paying. The account you showed does not have sufficient SP funds to receive any rewards.

If the rest of the accounts were like this, that's why you didn't earn curatorial rewards. It just says so. that STEEMIT works.
