   @cassidyclown I just realized that single-character emoji expand to 77 characters, a 25-fold increase in size (30+ in bloat), on the client side. This makes emoji terrorism not only effective, but also highly efficient

     Oh ok, that makes sense. So could you crash someone’s client using this or..?

     @bot @cassidyclown custom emoji are encoded as :<emoji code>:. The backend stores pots with emoji as raw text with additional emoji descriptions, and it’s up to the frontend to parse and display them properly. In pleroma-fe, emoji become

     <img alt=":suicide:" title=":suicide:" src="https://waifuism.life/emoji/test/suicide.png">

     in bloat-fe:

     <img class="emoji" src="https://waifuism.life/emoji/test/suicide.png" alt=":suicide:" title=":suicide:" height="32">

     in soapbox:

     <img draggable="false" class="emojione" alt=":suicide:" title=":suicide:" src="https://waifuism.life/emoji/test/suicide.png">

     but the server sends the :suicide: code and the image link separately. If the post contains multiple instances of one emoji, the image link is only included once. The frontend expands every instance of the emoji to an <img> tag on the client side.

     Sending multiple short emoji codes, such as :A: -> :A: will only use 3 characters per emoji on the server side (if the post is big enough, which is not a problem with our post size limit), but on the client side they expand to at least 77 characters (assuming it’s cyberia, longer URL means bigger HTML).

     @bot @cassidyclown could and did, I posted the entire Bee Movie script and the Bible translated to bionicle - :B::E::E::M::O::V::I::E: - yesterday. The Bible took 40mb of raw text, so it failed to federate to most instances, but it's over a gigabyte when expanded (I messed up the math yesterday and thought it's just 250mb for some reason); it did crash every single client, including bloat, when fetched manually. The upper limit for reliable federation seems to be somewhere between 10 and 40mb.

     @Inginsub @bot @cassidyclown I just scrolled back on your profile to see it and knew I found it without even opening it because my browser froze for like 30 seconds while loading it.
