I would like to point out that this section is not correct. If we assume that we are doing this for anti spam we have to throw out any idea of that the user is not willing to violate the ToS out of the window. A client mod can automatically accept this check and so can a spam bot. Screen scraping if you want to be extremely primitive in your attack can do this or plain old AHK macros.
Yes for matrix due to having a fully open API and a complete expectation of third party clients we are more vulnerable to this as an attack method but well Discord is very vulnerable too. Its actually more effective as an anti spam method to lock your guild behind a react check done correctly than using the built in check if your attackers are just going in blind. If your being targeted specifically then well the checks have to be more complicated.
Point with all this is that No. This feature does not provide a proper barier to serious spammers on discord other than maby slowing them down a bit but that would be it. The section about matrix is something i do agree about since it makes it clear we cant trust this to protect us.

Discord is less vulnerable than Matrix in this respect, as Discord does consider this an anti-spam barrier. This section is not implying it solves spam, just that it might not be valued high enough to be worth considering an anti-spam measure in Matrix.

My point is that Discord is simply wrong in considering this an anti spam barrier unless they are doing Server side magic to use this as a signal to determine if their anti spam system should kick in and sanction the user.

Another method that reuses normal message rendering is pinned messages, which many clients already use, but Element can't display (by default).

Pinned messages have a different use-case than welcome messages.
