If you'd bought a Christmas Trash Scope, advertised in terms of magnification of course, and were going to sell off to the next chump in line, what would be a moral way of selling it?

Should you advertise it properly, in terms of aperture and focal ratio, or regurgitate would the original department said?

On the one hand, selling it based on its magnification is misleading, and hence why it is a sign of CTS, but then advertising it properly ignores the fact that the telescope was crappy enough to be sold on the basis of magnification.

One advantage to selling it based on its magnification, because it would test the buyer. Any responsible buyer would know to avoid telescopes sold on the basis of magnfication and if they haven't done the research to realise that, they deserve to get bilked out of a few bob.
