I don't know how "persistant" it is but hacker1001101001 sure has done a lot of untrustworthy shit, from plagiarism to ICO bumping to deceptive sockpuppeting and lying about it... if you don't care about that stuff in your guild it doesn't mean that others must not care either.

It looks to me like it's pretty much the opposite than what you're saying, as it often is the case with users that you add to your trust list because they talk/act favorably towards you - it's not so much about Lauda but more about your inability to admit that you're a poor judge of character.
