I'm in agreement. Despite what I might think about their cause (I support their cause), I can't get a bead on who actually is behind the site. The site is constructed in a very non-transparent way, a very scammy feel to it.

I have found that the ACLU links from their site to the Pardon Snowden site. Interestingly, Human Rights Watch does not link to the site, but seems to have their own petition (maybe connected?) and that's as far as I went.

Even with that bit of confirmation that this site is legit. I am not that promiscuous with my information.

Because they're not links, they're images.
