I have reported several times on Discord lists of users who keep creating new accounts and posting spam.
It is often one user who manages multiple accounts and collects the rewards and then sends them to ionomy or somewhere else.
They create new accounts months in advance to activate them later.
As long as blurtbooster votes on nearly every post, nothing will change here and the reward pool will continue to be abused.
Manual votes would be much better, also to find out more quality content and to appreciate creators.
