I wrote to firstname.lastname@example.org and got a canned reply. So I sent it back with some vitreol telling them to do me the courtesy of reading my carefully crafted message before sending me something straight off the boiler plate.
I got a prompt reply back saying that they had indeed read it and had passed it on to their engineers. I hope they read the bit begging them to remove my most important keywords from their spam filter ;-)
Anyway I at least know that someone read it before sending me all of their fluff and links to "How to build a crawler friendly web site".
