The domains are nothing special, but are not crap (e.g. GreyMarketing.Info is on auction now with F$50 as a starting bid). If a domain costs $7 (F$1400) to register, I don't see why one would sell it for ten times less money.
If they need money there is the "Post for F$", they can make F$100 in a few minutes.
Sorry, I still don't get it...
