DDoSing a website, modifying their archives surreptitiously to serve their own wants (which was what tipped Wikipedia towards banning their use), running weird sockpuppet campaigns to build dependence on them, and fucking with Cloudflare's DNS resolution to prevent anti-tracking measures from working.

Oh and even if I wanted to ignore all of this, I couldn't use them anyways because they blackholed the majority of Finnish IP ranges after the DDoS incident to I guess punish the entire country for the targeted blogger being born here.
