"But Chesnut warned that sellers are usually nervous of including information like names, addresses, and telephone numbers on auction listings."</font>
In the UK, and probably throughout Europe, its a LEGAL REQUIREMENT that every business seller puts their name and address either in the listing or on their ebay ME page.
Probably more than 50% of ebay sellers are NOT simply selling their unwanted presents or used items, and are therefore very obviously buying to sell.
Why, therefore, do 50% of the UK listings not obey the law and contain the name and address of the seller?
And why, therefore, does ebay aid and abet these sellers by failing to provide an effective mechanism for reporting business sellers who fail to properly disclose their name and address?
At the moment, these people can probably only be reported by Trading Standards -- and sadly, there's no evidence that anybody from trading standards is doing its job by enforcing this part of the law.
Meanwhile, we can't complain TO trading standards because the seller often doesn't identify their location beyond "UK" or "London" and TS is far too compartmentalised to be able to deal with sellers who have no location.
So, its Trading Standards that are in part "causing" this problem and its high time that they made it a priority to set up an ebay supersquad that can deal with sellers in unspecified areas.
