Are HTML postings cancellable?
Most modern web browsers allow for posting to Usenet; they also generally offer an option to post messages in HTML, for easier viewing by other browsers – at the expense of significantly larger post sizes and much-increased difficulty of viewing by the rest of the Usenet community. This poor mixing of HTML and Usenet has been fought tooth-and-nail by Usenet readers, moderators, and administrators, but the postings continue. One suggestion to stop HTML posting is to declare HTML posts to be binary messages, and thus cancellable under the bincancel rules. This idea has not been implemented, simply because HTML messages are not binary messages, under current definitions, and if the definitions were changed the consensus would probably disappear. In short: no, postings are not cancellable merely for being in HTML.
