We do not know what was important in that doxx.

Probably nothing and the DDoS hype was intentional to distract attention and highlight J.P.'s doxx among the other, making them insignificant.

J.P. might be the only one of the doxxers who could promote their doxx in media, and this made his doxx special, not the content?

Anyway, it made the haystack bigger keeping needle the same.
