I believe it's generally permitted for an author to reference their own work published on another site, if:
- It's on-topic to the OP's question

I believe that frankk has done this: the user profile says ...

Therefore I suppose that the references in @frankk's answers generally comply with these guidelines and don't automatically need flagging.
If you disagree, and think that the reference shouldn't be included in a given answer, then please explain why?
