You may link to non-official sites. It's fine. We have for a long time facilitated links to d20srd, d20pfsrd, Fate SRD, dandwiki and so on, where none of those are official. There's no problem here.
The exception is if the site is basically a piracy database. Our stance is to not link to such sites:
When we encounter these sources, revise the post to reference an official source instead — we don't want to appear to support or endorse their existence. I recommend you assume that anyone reading owns the books they need, so a feature/section name combined with a book name and page number will often be enough, and an SRD link would be beneficial if available.
As for legitimate non-official sites you may link to and reference whatever you like.
