From the FAQ:

> It's ok to post stories from sites with paywalls that have workarounds.

In comments, it's ok to ask how to read an article and to help other users do so. But please don't post complaints about paywalls. Those are off topic.

One of the very few things from the FAQ I think is wrong. The comments should be for discussion of the content, not how to get to the content. The latter is the what posting something is supposed to be!

Being in FAQ doesn't make it right.

Especially the comments about how “we’re not Reddit, it’s a semi-noob illusion.”

If we actually did turn into Reddit, or start acting like Reddit, we can’t say that, because the FAQ is in denial?

Complaining about how it used to be better is itself a particularly annoying Reddit-ism, so I can see why they’d want to keep that sort of thing out of here.

Likewise something being a law doesn't make it right either, but one should still follow the law of the land for the most part.
