I decided to register at tc.com to see what all the fuss was about. I registered last night at 9:30 pm and received a sponsor offering by email about 90 seconds later. While I was tending to that matter, a second sponsor emailed me (about 6 minutes later) offering his sponsorship.
The first sponsor is a "Garbologist" from Lake Powell with "being outside/nude photography" listed as his/her interests. He/she has no less than 62 other sponsorees. The other sponsor is from New Mexico (not Arizona, were I live). Both were unsolicited, and neither asked me any kind of qualifying questions.
Bottom line . I guess anybody can become a member with little or no effort. (Not that there is necessarily anything inherently wrong with that.)
