I feel vaguely responsible for the trend that prompted this warning.
I don’t think there’s a thing wrong with sf/f authors reminding readers (and potential awards voters) of the work they have eligible for award consideration. It’s a larger field than ever, there are more outlets, online and off, and lots of stuff slips between the cracks even when people are actively paying attention. That said, you want to avoid getting all Chill Wills on people. There’s a difference between saying “this is my eligible stuff” and “Oh God, if you don’t vote for me I’ll die,” or something of more moderate phrasing but similar subtext.
Basically, remember that dignity counts. You can remind people your work is out there. You should let others (preferably people you have not planted) make the argument that your work should be on a ballot.
