njw the mods are serious about the "Linking to illegal sites is forbidden. If you bypass this censorship, you will be banned" warning. It is one of the very few things which will get you banned. Even scamming (normally) won't get you banned. That entire domain and similar sites are off limits
My apologies. I'm new here, and hadn't read the rules closely enough. I did include the relevant section from that site in my posting so that visiting the site wasn't required, but didn't consider that linking would be frowned upon. Won't happen again.
An expensive but comprehensive solution would be to operate a remailer service (possibly funded by bitcoins) from a country which still protects privacy. The postal mail equivalent of a VPN proxy.
I had to reread that about 3 times before realising that you weren't making a confusing reference to remailer software... I spent too much time playing with anonymity stuff! Anyway, interesting idea.
If you are in the USA USPS needs a warrant to open mail
That's interesting (and great), I didn't know that. I imagine they must be in the minority, though.
