One of the more interesting Wikipedia Article As Corporate Attack Page Via Original Research pages you'll find on WP:
http://en.wikipedia.org/wiki/VDM_Publishing
They might deserve it, but you've got to admire the abuse of Wikipedia that a very upset German can unleash. Especially ones involved in a lawsuit.
It's also interesting for "Wikipedians" as it involves profiting from reprinting your free labor. But still....please follow your own rules for sourcing and NPOV.
This section alone is a poster child for WP:MENTAL

vdm has been discussed before on here, i think. my avatar is taken from the badge they put on their books after some initial complaints.
i love that the wiki article attacks them and consistently stays that way, because the group are total bottom dwellers. maybe someone can do the same to the http://en.wikipedia.org/wiki/5-hour_Energy article, i'm completely tired of that obvious drug being hawked like a health energy drink. screw NPOV!
