I have to agree with cootsnuck here. If you are one of the people that found it necessary to raise red flags in these comments about this web site, here’s why I think you got your level of paranoia wrong in this case:

1. The site was never going to scale. The guys are printing physical letters and hand-inserting them in envelopes with stamps, for free!

2. So some entrepreneurial folks on the internet have gathered a hundred physical addresses, and they know a self-reported name and IP address, and maybe some persistent cookie info about a human that might be the first person’s friend. So what? Go bring up https://www.beenverified.com You can gather more info there in 15 minutes than the Continue and Persist guys will get over their whole project.

3. Learn to recognize a fun project that was done out of kindness and a spirit of adventure! Yeah maybe they should have not put up the language of “we get to sell your data if somebody offers to buy our web site”. But so what! The whole thing is just a kind adventure that brought a smile to the faces of some strangers, and will never be more than that. I appreciate it!
