That is a very good question.
First, it is a short list because not just every account that looks suspicious to me is on it, following some "Sherlock" logic, or assumptions of GenAI usage. I do not publicly discuss my doubts, but I may retract recommendations or boosts, until I have found clarity.
Currently, I'm checking factually incorrect claims, and demonstrable unwillingness to resolve the questions that arise.
Most of the more organized verifying initiatives I have listed in my pinned post are carefully updating their public documentation, for good reasons. Most fundraisers, in turn, are very specific in describing the respective family's situation, and who has verified them, and how.
If somebody claims to have been "verified" by one of the popular initiatives, and looking them up does not produce any evidence, I usually contact the respective account with a polite request to point me to that evidence. Multiple times.
E.g., the legit #GazaVetters are putting much effort maintaining their spreadsheet of fundraisers, and they clearly state on which row they need to do research work, and which of their recommendations they retracted.
#GazaVerified links back to the respective Fediverse profile, so the green check mark is an even faster check; I also contact Aral, from time to time, to ask whether a specific account is pending verification. (Gaza Verified meanwhile has coded a pending status indicator, too, so this is also easier there).
Some scammers, for strange reasons, never reply, never fix their factually broken claims, but keep addressing me under each and every new account they're creating, under their respective "brand".
This is what triggers my research, I'm not actively hunting for scammers. This is also why I only listed two very persistent scammers, and that list won''t become a very long one, as far as I can see, because my time is limited, too.
I'm not sure whether this sufficiently answered your question?
