:I'm tempted to agree with you that you are the only one arguing for your edits, particularly since your past supporters were blocked for sockpuppetry. The sources you provide, however, are not reliable by Wikipedia's standards. They mostly are mere list or directory entries, not detailed coverage, and they're not subject to any editorial oversight at all. The best source by far is Der Spiegel, and I don't think "rumor allegations" is an appropriate heading for what it reports. Rather, it's a deliberate whitewashing, intended to minimize the unsavory facts. That Spiegel article, the most detailed coverage and at the same time the most reliable source, should not be shunted off into a section on "rumors", but made the basis of this article, according to the policy on due weight of sources. Regarding the list of supposedly "notable people", I don't think we had articles for most of them, nor was there independent coverage discussing their supposed degrees, either.  
 :Finally, regarding the website, the mere fact that the other website also had some support in sources, say here, should give us pause. There's also, for example, this and this. (Fun fact: Their Google Maps map shows the university is located on the General Cemetery of San Jose.)
