It has been my experience that any time a list/newsgroup experiences such vcard/HTML/text attachments, a posting by a newsgroup/list regular/moderator normally serves to educate and such postings tend to not occur very often after that.
Ditto for vacation messages.
Attachment of files needed to explain a technical point are sometimes OK, but it is better to include a URL from which the file can be downloaded, or offer to send the file to those who ask off-list.
