Been hearing this is a problem again. Don't be a dick in bookmarks, folks. And yes while I made this image, I'm giving free rein. Take it. Spread it far and wide. Because I'm hearing that some readers don't know that their bookmarks are visible. Editing for clarity, since it's hit 14k notes and I'm tired of repeating myself:

No, I do not care if you think bookmarks are for readers. They're permanently attached to fic- which means authors see them. Authors, you may be shocked to learn... are also readers. So they also read fics- troll bookmark lists for good fics. They check their own bookmarks, perhaps, or stumble upon them in their search for new fic. It is not censorship to ask for respect. Or kindness. Leave your notes, leave your chapter count, leave your additional tags and thoughts, that's all fine. But you can do that without being mean. Because fandom is a gift we give to each other, shared freely. Treat it with kindness.
