Is an original paining of Mona Lisa worth anything to you? Probably not.
Is it worth something to someone else? Yes.
Just because you aren't interested, doesn't mean someone else isnt. An account with this UID that hasn't been closed is RARE. Thats what gives it its value. It's worth more than you think. Besides, this isn't an account sale. It's collateral for a one week loan.
Goodluck with your knowledge but as far as I know an account is not similar to a work of art. An old account is of no value here because it will not benefit you in any way. Anyway, knightkon seem interested in filling the loan.
Well its quite wizzard to see a such low uid rank account here at this forum active, this accounts looks like camed from the hacker attack here, as the activity of the accounts returns just today from 2010, even being something rare and without adress. I dont see any problem and there is a market for accounts with uid low, thats why knight is interested.
