I've seen several items posted for sale recently where someone will put up the full description, price, where it ships from, etc, but then says "will post pics later." Then they come back a day or two later and post pics, sometimes followed by additional pics a few days after that. Is this a sneaky form of bumping? I try to make sure I have everything in the initial ad so that it's nice and clean on the first post, but I get bumped out a lot of times by people posting "additional pics" etc. Thoughts?
