A minor update has been made to the general guidelines. A new point has been added:
9. Don't promote or link to fan translations that either cost money or require you to make money for the patch creator to get. This includes things like patreon-only patch releases and using ad-infested link shorteners for downloads.
This was occcasioned by a certain site deciding to MTL VNs on a mass scale then using ad link shorteners to access them (or you could donate :>).
It was somewhat difficult for me to place where this was actually supposed to go, but the forums where translations may be discussed are diverse and such topics could pop up both in tl projects, fan tl discussion, and visual novel talk depending on exactly how they'd look, so there's really no other realistic solution than a global guideline.
