Very interesting question, Jim.
I used three different snipers during the last years, but never got an information that the sellers has changed the listing.
Maybe the sellers never did this, but I think that the snipers does not check it. I will ask my current snipers
if they do that.
I use the (german) sniper www.mysniper.com and sometimes the free version of www.hammersnipe.com
