I’d rather them being prohibited, so as to have a solid reference on how to act, that it be left an arbitrary thing depending on the criteria of different discrepant individuals. I was actually looking for a quote of the matter from the higher spheres of the forum, and came across this:
https://bitcointalk.org/?topic=5197446.0The quote in the first post seems like a non-real-quote (as shown by the note at the end of the post, the wrong pointing quote link, and the fact that there is no such post made by @theymos, neither on Bitcointalk nor any of the archive sites I’ve looked at), but it gives an idea on how arbitrary the criteria can be on such a matter.
Whilst people are bound to differ in opinion on the topic at hand, or to the shades of grey implied as exemplified by the above referenced post, it does seem an overall conceptual conflict to allow account sales, but to discourage them, and even lead them to be tagged for it. A more logical approach would be to prohibit them (try and control that though), and report proven cases for appropriate action to be taken to either party.
