Aside from all the above mentioned comments regarding Ebay in hk.
They also have a completely useless support and feedback admin group.

I wrote to the feedback group (using the horrible live chat they have) regarding the fact that a group of sellers flood all of Ebay HK with their crap items (shitty mobile phones, low Q projectors, old comp hardware they sell in lots etc.) The reply i got from the feedback group was "if you don't like it go to Ebay.com instead".
Very productive of them don't you think?

And when i try to post something with my .Se registered Ebay account it gets removed and i get a msg saying a 3rd party has used my account and it the ad has been removed, and the account banned/suspended from posting or bidding on Ebay.
Nice work Ebay HK you truly suck.
