It might not have even been this board. I didn't think it would make a huge difference, because gmail puts all my crap in a folder anyway, but I unsubscribed from like 100 things and put the rest in that one email a day, and I love it.
I just did this, too. I had over 100 subscriptions in my junk email (most of which I don't ever remember signing up for). Thanks for posting this. Hopfully I'll have less spam to weed through.
