This is not a personal attack - it is a calm and accurate description of a thread on photo.net at the moment, concerning Bob Salomon.
Basically, a person in Canada sought advice on photo.net, relating to the purchase of a lens hood. They were recommended by Bob, a Heliopan hood. They then bought it from an authorised US dealer (a strong point in this case in their favour, but imagine if it wasn't).
For whatever reason, they then attempted to sell it on ebay, with the product being available to the US. They were emailed by Bob that they weren't permitted to sell this item (presumably 'to the US'), and a few hours later, the listing was ended by ebay at Bob's request.
What does this mean? If Bob's interpretation is always accepted by ebay, any attempt to list an item from outside the US, which would be available for purchase by someone in the US, would be immediately terminated if it was an item of any of the following marks:
Ansmann
Berlebach
Braun
CombiPlan
DF Albums
Ergorest
Gepe
Gepe-Pro
Giottos
Heliopan
Kaiser
Kopho
Linhof
Novoflex
Pro-Release
Rimowa
Rodenstock
Sirostar
Tetenal Cloths and Ink Jet Papers
VR
Vue-All archival negative slide and print protectors
Wista

Please don't let any sympathy with the OTT personal attacks there blind you to the point.

Anyone else unhappy with this situation?
