I really want self-moderate option to be disabled for newbies and Jr. Members only (I'm referring to the marketplace scams at least). There is another reason which I'm not mentioning here.
Because if a newbie/junior account scams and get tagged then they just create another thread in seconds and continues the process every time.

I don't think it will be unfair for them because if they are a genuine trader then they will easily rank up to Member and will get the self-moderation privilege.
If they are honest, do genuine business, earns trust from the community then 11 Merits can be earned in a short time I guess. I think members here will support those genuine traders.
