Is it possible or even a good idea to ban all newbie accounts from participating in any bounties. Make it a site wide rule. If this was added to an increase in merit for jr member to say 3 you may really smash these guys up for good.
I dont think it is a good idea. Dont think because i am a newbie then i dont accept with you.
For example:
Merit and rank on BCT is good for their Signature Campaign only. No more than nothing.
For other campaign as: Social, Content.... Newbie or JR can do it as a lengend. As you know, almost of member are newbie or jr now (I think it over 70% members of forum). What happend with they lost 70% advertising for their ICO? It really is not good ideal, The team will not accept it. They can leave their bounty in to other platform, it mean traffic for BCT maybe down.
For multi account, I think the BM should be harder in their manager.
