Yes, "someone."  This is what Wikipedia policy says about self-published sources even from an expert in his field: "Self-published expert sources may be considered reliable when produced by an established expert on the topic of the article, whose work in the relevant field has previously been published by reliable third-party publications.[6] Take care when using such sources: if the information in question is really worth reporting, someone else will probably have done so."  WP:SPS.  

It is obvious you, Ihardlythinkso, are here only to troll, and that you are neither reading the sources you cite nor are familiar with the slightest bit of Wikipedia policy.
