Although my experience over the last 10+ years on eBay has been very good
and without any problems I've seen many very negative attitudes expressed
about eBay and especially their lack of interest or help with problems.
Well, last night I watched a sterling example of eBay policing itself.
I had searched for a specific item and found a bunch listed.  But as I
browsed through the listings some of them began to hold my attention and all
taken into account they smelled very fishy.  And all had things said in the
adds that violated at least two of eBays rules.  There were 6 or 8 such
adds.  Well, stumbling through their support pages I found the place to
report suspicious adds.  Within 20 minutes the first set of suspicious adds
had disappeared.   I then did the same thing for the other half of the adds
I'd seen and again, withing a few minutes those adds had disappeared.
This is not the first time I've seen quick action by eBay when there was
something fishy going on.  On another list the I subscribe to that deals
with a very special and expensive small telescope from time to time we see
scam adds for these telescopes.  And on one occasion one that was known to
be stolen based on the serial number.  Reports to eBay about such adds are
dealt with by the end of the day and sometimes in minutes.
Such action by eBay is reassuring that they at least try to police things.
But still, Buyer Be Aware, when something just doesn't ring true or is "To
good to be true" back off and be very careful.
