/**
    Note: maybe change to have permissions
    Users can decide to not receive notis from people (blocked)
    Or below a certain value of ETH - can set custom amounts to be paid to get notifications
    Allow people to toggle "only x verified users" - although this would only be on the listener's end
    Listener gets event -> checks database -> if user is not verified, do not push to db if receiver has this permission set
    
    Maybe: Have our script verify here or another contract all x verified accounts
    This is very helpful to have verified accounts on-chain
    Would need some clean up routine to remove users if they are un-verified to verify another account
