Having it tacked on to their page wouldn't make it any less promoting. It would just be promotion...with the note tacked on. We'd still have to monitor and take care of their content as well (their pages have special lock settings and regularly skimmed for vandalism), and there will be people who won't believe the letter anyway, jump in and then look like morons.

For the record, any kind of negative criticism that isn't constructive is removed from comments on articles. There's a thread from a few months back (maybe even a year?) about a crack-down on such things.
