Customer? Judging by the number of obnixious Flash ads on Yahoo, I think you could have legitimately claimed to have crossed over to the 'victim' status months ago.
Sorry to see you go, markm. I enjoy reading your posts, but understand how frustrating it is for taking the time to write one and have it disappear. Yahoo does little to filter the stock promotion site spam <sigh...>, but is getting more aggressive at filtering naughty words. If you have your Message Board Settings set to filter profanity and Yahoo thinks it detects profanity (in any language) in something you're trying to post, it will disappear. Posting links - blogs or otherwise - doesn't seem to be an issue as far as I can tell. Who knows, though.
