'The ones I find most annoying at the moment are the 'This one hasn't sold yet? Let's update....' 

Yes - far from being helpful, these messages are usually completely irrelevant and unnecessary. I'm sure most of us know what we're doing, and just want to be left to get on with it, rather than have all these hints and nudges and silly phrases popping up all over the place. 

I also dislike those daft little notes on the item listing page, 'Hurry before it's gone', and 'Breathe easy. Returns accepted' - does eBay think a potential buyer might start hyperventilating if they aren't reassured about returns? 😂
