The thinking here is really shortsighted. It only works at companies where there are LOTS of people and lots of people with the same title.
Not only would it make for uncomfortable conversations at work, it would likely get me in trouble with my employers. I can't believe you're actually putting the company names out for people to read when you have SO little data. there is NO practical level of anonymity here. Lot's of folks can (and probably will) get in trouble.
