Luckily I've taken the "no effort" approach to extremes.

I haven't made the slightest effort to list anything on ebay for months.

Exactly the same amount of effort ebay would make to sell my stuff, if I did list anything, unless I "volunteered" to hand over 25% of the selling price as "promo. fees".

The ONLY thing that ebay does with my ads. is to hide them until (it hopes) I pay up.

No chance ebay, go suck some business seller's blood instead.
