There's this other competing explanation: Their marketing department is Cordo.
This.
Enthusiasm for an IP is not a zero sum game, it's a case where a rising tide lifts all boats. Excitement about D&D benefits DDO, NWO, and book sales, it's hard to imagine Hasbro isn't sufficiently market savvy to realize that.
I could believe they retain the right to review advertising material for appropriateness and the SSG marketing department (AKA Cordo) can't be bothered to go through the process, but I sincerely doubt it's a blanket ban on advertising.
I could also believe there was a ban when the Atari dispute was still raging, but again, that's not applicable today. Or that they intentionally don't want to advertise because they don't have the server capacity to handle a large influx. Or that they are locked in a contract with a marketing company that isn't doing anything (a la FernanDOH). But none of those are the same as an advertising ban today.
Believe what you want, but I'd need to see some solid evidence before I believed the "advertising ban" was anything more than innuendo, originally promulgated by shills and dupes and tacitly endorsed by SSG, to cover the DDO "marketing team"'s inaction

EDIT: I added "originally" because by now the longevity of the rumor has given it an undeserved credibility even a reasonably skeptical observer might fall for.
