 <li class="answer">
 <p>If you're on the fediverse or Bluesky, and you've opted in but now want to opt out, block the Bridgy Fed bot user for the network you want to opt out of. For example, on the fediverse, block <code>@[email protected]</code>. On Bluesky, block <a href="https://bsky.app/profile/ap.brid.gy">@ap.brid.gy</a>.</p>
-<p>Also, if you're on Bluesky and you've <a href="https://bsky.app/profile/safety.bsky.app/post/3khhw7s3rtx2s">hidden your account in the logged out view</a>, Bridgy Fed interprets that as opting out and won't bridge your account.</p>
+<p><em>Warning: right now, this can't be undone! If you opt in by following a bot user for a given network, and then opt out by blocking it, you can't re-enable the bridge by unblocking and re-following it. <a href="https://github.com/snarfed/bridgy-fed/issues/783">Hopefully this will be possible in the future.</a></em></p>
+<p>Once you've done this, Bridgy Fed will no longer bridge any or your posts or interactions in to that network. It also deletes your bridged account in Bluesky, but not (yet) your bridged account in the fediverse. <a href="https://github.com/snarfed/bridgy-fed/issues/783">We're working on it!</a></p>
 <p>If you're on the web, feel free to <a href="mailto:[email protected]">email me</a>, or you can put the text <code>#nobridge</code> in the <a href="#web-profile">profile on your home page</a> and then <a href="#update-profile">update your profile</a> on <a href="#user-page">your user page</a>.</p>
