Opinions on doxing?

It's a paradox, no pun intended. There's an incredible amount of work done to make communications more anonymous, hidden, or protected, either through encryption or entirely new protocols / projects. This is the whole premise behind I2P and other services. The strongest point of the Internet is the anonymity behind it, which protects people's security and serves as a reassurance that they can't be removed for what they say. By deanonymizing someone, you're taking that security away from them, and opening someone up to infringement.
