When the bounty reports are no longer needed in the thread since many bounties moved to google form for reporting their weekly reports but still they will be reporting on the thread itself which is spam and its against the forum rule too so ban can be implemented on those accounts.
I think admin/moderators doesn't read rules of bounty. In this case if bounty report doesn't require but still bounty hunters post on the thread then we should report against the bounty reporters who break rules if so, admin/moderator would be able to take action. Either admin/moderator will remove the post and/or will ban the bounty hunter if require.
Not much people were banned for the reason of breaking this rule,only their post got removed sometimes but we can't report all those reports since the bounty threads were filled with hundred of pages with different users posting random so what can we do to stop them is giving ban to them or nuke if they are newbie.
