You must be marking your spam incorrectly, at least not in the way that the gmail devs imagined. I get a ton of "me" spam, having never hidden my email address and not changing it for 10 years, but they always end up in the spam folder. (added my personal domain to gmail back in 2006) For as long as I've used gmail, I've just hit the "mark as spam" button, never blocked individual domains. Apparently, YMMV.
