A friend of mine told me that Hotmail (like Yahoo) had "reset" everyone's preferences about being listed in their directory and/or subscribed to 3rd party email solicitations. I checked my "options" et al, but never saw anything out of the ordinary. I couldn't see where anything had been changed/reset. I get my fair share (15-20 per day), but I've also used the address on quite a few sites (reputable or not) for many years.
