I read your earlier thread about all this a month or so ago - and was thoroughly impressed with your methods and tenacity.
And I love how you managed to track down those with financial deep pockets (like the real estate guy) - to hit them hard with the settlements.
A few years ago I remember a colleague in the bdsm/fetish market that once said he made more money pursuing copyright infringement cases - than he did with his websites and video production (and he was considered a BIG producer in the niche categories - his name was fairly household familiar).
He'd go after a few infringement suits each week and wind up settling for rather healthy settlements. Like you, he primarily targeted the ones he knew had the money to pay.
Kudos to your ongoing efforts. I really hope more producers read about your exploits and get inspired to do the same.
And a special round of applause for donating portions of your settlements to worthy charities. That puts you in a very noble category.
