We've all jumped on Tomas, but I suspect that the word 'open' was
missing from his summary. I've worked in e-commerce environments
where we deployed tools that checked whether orders with high risk
scores appeared to come through an open proxy, and unusual browsing
patterns were detected and investigated for the same.
I wont give the game away, since some of the people on this list will
be able to work out who I am talking about :-) but open proxies are a
source of fraudulent orders, and also competitors spidering e-commerce
sites for price and availability information. Making it harder for
both was an important job - both groups of troublemakers would look
for a softer target elsewhere.
