I get em all the time, but not that lengthy.. usually just something like, "HEY! remember me? Sorry I haven't gotten back with you til now.... yada yada... then goes on to something like, "I finally posted the pics that you wanted at.... then gives a paysite url or some dating site..
I guess they think people are that gullible... and I guess some are or they wouldn't be sending this type of spam..
