I sold an item a couple of weeks ago, got full asking price within a couple of days. But when I checked out who the buyer was, my heart dropped! He had no feedback and became a member the same day he bought my item. Payment went through fine, but communication from buyer was 2 or 3 word replies. Obviously not a bot, but scary. Since he was a new member I gave him positive feedback. He did compliment me on "smoothest online transaction he ever had", but he gave me no feedback. I'm an old member and am amazed how things have changed.
Sorry if a bit off topic. And yes, Tammy is always quick to respond to any of my concerns. I'm glad they are stepping it up to block the bots!
