People don't agree with other people, all of the time, so of course a down-vote is necessary. It shows disagreement, but that shouldn't equate to having the post removed.. Voting and reporting are two different things. If a post is inappropriate, then there should be a 'report post' button.
I have a dedicated safe spot, which is weather protected. I place my parcels in the safe spot as soon as I've booked them. If they're out overnight, so be it.. they're not going to get rain damaged or stolen. It helps that I'm up a drive, not seen by the roadside.
I search under 'latest listings' when I'm looking for something inparticular. Based on a 'latest listings' search, you could always shorten your listing duration.. try a 3 or 4 day listing.. that way, with each relist your listings will be back at the top of the list, under 'latest listings'.
All I do is deactivate the product in My Products. Then go into the live listing under Items I'm Selling and edit the ending time to bring it forward to the earliest time slot it allows. Simple.
