@AD888 @Eridian Thank you for the proposal!
I personally support the initiative of building such a tool. I see a pretty useful use case for the tool, where we could use High Signal as a part of the Independent Stakers Identification framework mentioned in the scope of CSM v2.
If we assume this is true and High Signal will be used for this purpose (in addition to other tools), then the answer to the quoted question from my point of view is the following: it will be up to the Lido contributors to propose the criteria and parameters of the tool to the DAO, and up to the DAO to decide if the overall identification system is good enough or not (via Snapshot vote, I’d assume)
