It looks like Yahoo Finance requires some form of proof that a company person requesting a company profile update is actually a representative from the company!
For example, it makes sense to me that knowone can contact Yahoo Finance and ask them to update Amazon's corporate head office address without providing some proof of their credentials with Amazon.
Why does this matter?
Someone with WPMLF credentials offered this address to Yahoo Finance or Yahoo Finance retrieved said address from another known source. In either case, this is evidence to show that the WPMLF is alive in San Diego, California until further notice!
