It basically only was that step. From what I see there are already some discussions in your comments.
The reason for that specific advice is the report button. People do report suspicious games now and then. And from my experience, a missing reference where there could be one raises suspicion. Though I often see that link missing. Maybe Patreon had or has some policies against linking to other sites at some time? I do not know.
And one can assume that games can be put into quarantine after a report, after all, that's what that button is for.
