I hear pedophiles shop at Wal-Mart, too!
They might, but I doubt that:
(1) Wal-Mart's CEO is an internet porn mogul (Wikipedia's owner is)
(2) Wal-Mart's distributorship is run by a guy who got caught soliciting prostitutes (Wikipedia's arbitration committee is)
(3) Wal-Mart store managers approach the pedophiles who shop there and thank them for "cleaning up" the aisles in the toy section (Wikipedia's administrators frequently praise pedophile editors for working on articles).
The problems at wikipedia are entrenched and sanctioned at the highest levels of the site.
