here's the full lowdown on test items can cause your ecrater store to be deleted (from an email I received from Dimitri):
Currently there are more than 6,000 sellers on eCRATER and if everybody starts to post test listings it will become a mess. Of course the seller can test his/her store but it must be put on hold first (refer to our terms)
So I created a crawler that primary goal was to enforce the compliance with the terms.
The crawler is smart enough to count the number of your items and anylise them first.
If you have more than 90% of items that comply with the terms, only the items that do not comply will be removed.
If more than 90% of your items do not comply with the terms your store will be either:
banned - if you have more than 20 items
removed - if you have less than 20 items.
So, if your first listing is a test listing, it will cause the store to be deleted (if store is not put on hold first).
If you have 10 real items and 1 test item (and store is not on hold), the test item will simply be deleted.
If you have 8 real items and one test item (and store is not on hold), your store will be deleted.
(not sure what happens if you have 9 real and 1 test item, since that would be exactly 90% in compliance and Dimitri said if MORE THAN 90%)
