I got this message on several different discussion groups. Strangely, they were all (purportedly) from different people. I'm not sure I believe this -- they may be pseudonyms. In addition, the commercial non-community style of the messages seems especially inappropriate (revolting?) to me; in particular, the subject line that gives no clue as to the marketing nature of the message.
I've seen discussions on lots of groups about the appropriateness of job postings on lists, most recently on Singapore's Ruby group list. Most of the people who weighed in said they didn't mind as long as there was something like "[jobs]" in the subject line. Perhaps this would also be a good approach for marketing services such as this training -- a tag like "[marketing]". I personally wouldn't mind marketing messages whose subject lines disclosed their nature, as long as the subject matter were relevant to the group, and especially if it were community members offering the services.
There is an overlap between the Ruby and iOS developer populations, so I don't think the subject matter is entirely out of line.
Of course, posters of messages like these would probably not comply with such a suggestion, so we'd wind up banning them just like we're doing now.
