The links are to accusations, not evidence.  Sure, Trust can be abused, but not BespokeServicesLTD Trust.
If selling trust was bad, I'm sure theymos would have made a rule against it.  He didn't, and here is why:

You can't ban selling Trust, there's no way to enforce that.  Trust would still be bought and sold, but newbies wouldn't know about it, so they won't be able to protect themselves.

I'm selling my Bespoke Quality trust in the open, on Bitcointalk, so newbies would know it's done all the time and will be more careful.
Just like selling accounts.
You're not against selling trusted accounts, are you?
