<div dir="ltr">This may be slightly off topic to key validation, but imho the ugliest part of keybase is the URL paths. For example, I may have reigstered <a href="http://github.com/user1" target="_blank">github.com/user1</a> and <a href="http://keybase.io/user1" target="_blank">keybase.io/user1</a>, but an attacker may control <a href="http://twitter.com/user1" target="_blank">twitter.com/user1</a>. <div><br></div><div>I believe many users will believe <a href="http://twitter.com/user1" target="_blank">twitter.com/user1</a> == <a href="http://github.com/user1" target="_blank">github.com/user1</a> .
