I can confirm this. I am not proud of it because, not only does it break Wikipedia policy but was unethical and done for an unethical person, but one of the first tasks I was given at my first salaried job was to make a wikipedia page for the boss (he said that his publicist told him to get one done). The safeguards at Wikipedia almost held, but he had me battle the editors for weeks until it finally got done. I left a couple months later because he kept doing (and asking me do) unethical things, and wish I had the wisdom and courage then to have said no and quit on day one.

My company has an entire PR team to get our execs in 30 under 30 and 40 under 40 as well as update their wiki pages!

You might consider revisiting this on Wikipedia. It's probably not too late to remove the boss's promotional page.
