Think you where already mentioned in OPs open address.

If this is about bitcoins reputation around the web,there are a lot of other areas I would target as well.
Racism,sexism and homophobia are great places to work on if you want to change bitcoin into more of a mainstream tool.

Lending is also a predatory business that mostly goes after the people that are going through a rough patch or are stuck there.
So if we want to eliminate giftcard scammers,we should also be looking to wipe that aspect clean.
If thats the case maybe the transacting in accounts as well,because that to leads to scamming and misleading posts.
Maybe limit one account per person and be done with it.
Create a peon system where only the anointed few at the top can select one lucky account to move from Junior to member where he must suck hole for 2 years to become full member.
If shady business is the real issue wipe the whole aspect out,not just something that detracts from other business ventures.

When you create this it will turn off more people then you think. Already a bit of a issue with a closed shop mentality on some sides of the forum.
Add a lynch mob with powers and its a quick ride to the bottom. But I know I am in the few on this thinking and will let others speak.


Also suffer from paranoia
