Is anyone else being inundated with emails trying to sell knockoffs of high end watches (Rolex et al)? I have been receiving several of them a day for the past several weeks. The emails include no Unsubscribe option, just a teaser line and a link. Apparently they are pretty resistant to spam blocking, too. Usually after I mark something as junk once or twice with Thunderbird that takes care of it. Not in this case. The "senders" keep changing but the subject lines and content don't vary much.

Not important, obviously, just wondered if anyone else is experiencing the same thing. And wondering a little about why some spam is more impervious than others.
