If I could be bothered to sort out my "spare" domains to the point that they all pointed to the same place, I've definitely got over $100K a month. Most of that is traffic from old sites, not pure typeins of course...
Put another way, 100,000 a month is only 3,300 a day. That's only 66 domains with 50 a day each or 132 with 25 a day each (low numbers for expired domains with traffic from old links)
Put still another way, if somebody owns 30,000 domains and doesn't even get $100K visits a month out of them, they're IN THE WRONG BUSINESS
