Nope, but I've only traded on here, and not much. I think there was one person who, when we were trading A BUNCH of items, ended up forgetting one. But I didn't really care, since it's an easy mistake to make (God knows I went through the items I was giving, like, a dozen times

), so I didn't even mention it. But, I also only leave out the items I'm going to trade (this is actually more about just not liking the look of a lot of junk lying around, I keep my extra DIYs in a side character's house- and I will until THEY FINALLY LET US PUT THEM IN STORAGE

), so there's not a lot of trouble someone could cause. I guess they could steal fruit, which would be rude, but it'll grow back. Besides, I usually harvest exotic fruit right away, and I don't care much about peaches- I usually leave a few stacks out anyway in case anyone wants them.
