Tor is slow and has a reputation of being used by pedophiles and drug traffickers.

It sucks that literally using something that should be the default, truly protecting privacy, has such a bad reputation because… well it protects privacy.

You work in the US, right?
I’m so sure that this would be absolutely illegal in the EU. Privacy laws are rather strict here and I can’t imagine that it would be legal in any way to say that you’re doing an anonymous survey if it isn’t actually anonymous.
