Hi!
Well I've seen and asked too many people already for items they're selling and in the end they already sold them. And I bet it's contaminated with much more... You guys need to find a new solution to this as it's a pain in the ass and then you end with like 300 ads for just a region and in the end you have like 200 real for sure.
One of the ideas is to put a timed ad... After 3 weeks of not notifying if sold or remove if given up for sale the ad should delete itself and user must add it again.
The Marketplace feels like a jungle now...
Cheers
