The existence of GoI-XXXX is not to be disclosed on any official documents.
Isn't your very article an official document which discloses the group's existence?
[[AUTHOR'S NOTE: this part is intended to link to a page tagged "collaboration". I have no intention of actually writing a testing log because "opposite" is really subjective and thus it could get quite sticky. For instance, after pitching my skip to site19, someone in chat asked me what the opposite of a pineapple was. Yeah, seems ridiculous, doesn't it? A collaboration article is the next best thing in my absolutely unqualified opinion.]]
In terms of a test log (even for a collab), the author needs to pull their own weight and is responsible for showing how the anomaly works. If you do not show it, how will anyone else do their own takes on it?
As per the recurring criticism, I can agree with the confusing aspects of it. You begin the SCP with the geas with a specific effect, and then divert to additional effects and spend an unusually long time to talk about the natives (which feels like a separate thing altogether). You never really went back to the main point, the core anomaly. This makes the article very shaky, if the core is already so vague.
Thus, my advice here is to forget about the additional effects, the natives, the logs, the Thaumiel etc. Focus on your geas and how it works as an SCP before you add on the garnish.
