Actually there are. 30 ships on an alt account, let's make it an endymion, it yields approx 10k if you sell it to the AI shop so in total 300k. I've got 5 alts with SoLs made specifically for that purpose on 3 of them, the remaining 60 ships are ships I actually want to keep - I'll have approx 1.5 million after the wipe, not withstanding the 500k from the clan warehouses, and 250k from the accounts.
If they really wanted to test the economy they'd wipe it all. As it is it's not going to show anything other than I'll be the richest man on the server again right after the wipe..
