OK - I'll put my hand up as being one of the 'rude' ones.
It's down to the changes at eBay - mainly with the feedback system. Not being able to leave a neutral or negative for buyers is just plain LUNACY!
I no longer bother to leave FB nor do I expect it on the (now) very rare occasion when I sell something on eBay.
The eBay FB system has 100% lost its value IMO - in fact most of the changes there have DESTROYED what was once a great place - I hardly bother anymore and that's sad coming from a seller that USED to sell over $30K a month there.
