This contains some broken links:
But it can not changed, because it is locked.
Can someone fix this?
You cannot fix it yourself, however, a moderator can. Flag the post for moderator attention and explain the situation ("link in text xxx is broken, could you replace it with yyy or remove it?").
Now, if it's historically locked, as this question is, you almost did the proper thing. Ask on the Meta of the corresponding site to bring attention to the question.
Note that this question was originally posted on Meta Stack Overflow. This question is currently on the correct site, as it was migrated.
I've taken the liberty of fixing the links - there was a request to delete it but I figure there's a little life left in the question, and I kind of did a bit of a workflow to try to fix these.
Custom flag the (this?) question explaining the situation and the value in fixing it. If nothing else, it makes sure a mod sees it. Link the historically locked question too, and any information that's helpful to provide context.
Flags suck a bit in terms of nuance - if you can give corrected links to be fixed, it's awesome. As we're wont, I ended up creating a gist with the intention of workshopping it and fixed it on my own (I got distracted). This is in no way mandatory, but if I was telling someone else to fix it, it probably saves a lot of effort, and ensures we're on the same page. As suggested in the comments, I guess.
