Especially the part where he uses the word "regulatory" got me thinking. The forum's mission is to be as free as possible. That includes allowing people to hunt scammers, but it makes it very difficult for new users to have the freedom to do business here.
I think we need to have some kind of balance between giving total control and total freedom for everyone to write whatever he wants.
Speaking about scams in forum, I think that situation is better now than it was few years ago, there is less stupid scams, but forum activity is also lower.
And I also know genuine users who got scared by evil fee during registration, and they never wanted to fully join bitcointalk.
