@Esanders: do you have an example page handy where I can test this?

I tried to test it as a logged out user on a protected page, but I guess the talk page for a protected article can still be editable by that user, so it's showing the reply links.

I don't know how to find out protected talk pages.

You can use Special:ProtectedPages to find some. (Or just make one and protect it, at least on Beta, let me know if you don't have some user rights and I can grant them.) And yes, talk pages and their corresponding article pages are protected separately.

Here are some examples:

• https://nl.wikipedia.org/wiki/Speciaal:BeveiligdePaginas?namespace=1&type=edit&level=autoconfirmed&size-mode=min&size=&uselang=en
• https://nl.wikipedia.org/wiki/Overleg:Rocky_Marciano

@matmarex: I tried couple of protected talk pages on Dutch wiki, but I am still getting Reply links on those. I tested on the following pages:

https://nl.wikipedia.org/wiki/Overleg:Fred_van_der_Wal?dtenable=1
https://nl.wikipedia.org/w/index.php?title=Overleg:De_Chninkel&dtenable=1

Depending on their protection level, your account might still be able to edit them… :) Try it when logged out.

no wait, I tested while I was logged in (my account probably has some special rights that I don't know of/use?).
When I tried as an anonymous user, it's not showing Reply links anymore on those protected pages.
