They definitely are not a 501(c) non-profit. The BFRO is incorporated in California and under the laws of that state had to identify itself as an entertainment company (rather than, say, a hospitality or service company). I will note for anyone that wants to find them that there are at least two BFRO threads extant before this one - both may be available only to premium members. IIRC, one focused on a near implosion of the BFRO and the other was specific as to the expeditions. I believe, but will not swear, that the information required to find the BFRO's business license is in one of those threads.
For both Norse & VAfooter, not sure where I saw it, but sometime after Finding Bigfoot went big, they announced that they were going to start obscuring location data. They also started putting bigger boxes on their map set to hide precisely where an encounter occurred. They stated that the primary basis for doing this was to protect the privacy of witnesses. Which is a good idea - I've been to the specific location of two New York incidents reported on in the Baby Bigfoot episode and have been able to identify other specific homes and phone numbers from reports made before they adopted that policy.
Same as what WSA said - not a member and no collateral involvement with the BFRO but their database AND the reports they make public are a gold standard for the 5 W's of an encounter. Compare certain other "research" groups whose reports read, "Yeah, I saw a bigfoot at Aunt Em's house and shot it and made steak out of it." And weak tea like that gets posted as an "encounter."
What the heck is the SSR?? I must be confused. Often am.
