It seems to be taking the piss somewhat for an anonymous 'Guest' to complain about the fact that the clones can masquerade as Guests.
Is 'Guest' trying to suggest that those who do so much to help the site, and are trusted to act as 'clones' should have less facilities than the 'Guests' themselves.
Membership has its privileges; and any 'Guest' can access them by taking membership. That they choose not to is their prerogative. The least the 'Guests' could do is identify themselves with a consistent 'handle'. That this particular 'Guest' chooses not to should not mean that his/her comments are any less valid than those of a member They are just unattributable!
