You are not going blind, there is no visible marker for "blocked" at this moment.

I guess it's supposed to be displayed in line with "nsfw" and "long/short", but there's no code for it, as far as I can see.

Video tagged as nsfw+long:
<ul class="notes"><li class="yellow">long</li><li class="red">nsfw</li></ul>

<ul class="notes"></ul>

Nothing there. Might be a case for the almighty @lucky760

Wow, I found another bug??

This is one of the few things that was completely overlooked in the redesign, and one of the many things still collecting dust on my to-do list.

So you can't add a color/text about it somewhere?

It's not that simple because it has to react responsively when the page size changes and it has to always have a place to fit among all the other similar flags.

Oh.
