Monitoring caught this rather than me noticing, which is the one part of the story I'm happy about.
Placement went live in December, 400 through a broker I've used maybe eight times. Article still exists at the same URL. My link is gone from it. The rest of the article is unchanged, including two other outbound links that aren't mine.
So this isn't a site cleanup or an editor purge. Somebody went into one article and removed one link.
Broker's terms say "permanent placement" with no time qualifier, which I now realise means nothing without a number. Opened a ticket four days ago, nothing back.
IME people either shrug at this or don't check at all. Has anyone here ever actually been refunded or had a link reinstated, and what did you say to get it?
