As far as sources go, I think a lot depends on your style and preferences for learning. There are a lot of folks that put out daily or almost daily videos going into recent Q drops and other related news around these.

Its pretty hard to rate by effectiveness and usefulness since these are all such subjective properties, but if you looked at the researchers that get attacked the most.. then that perhaps is a good indicator that they are over the target.

The big youtube deplatforming wave on Oct 16th hit the below people and channels for example - I've left out X22 and IPOT from this list as you already know them. Clouthub also has a huge number of Q people on their channels however they had their video-hosting service terminated.. and are trying to find a new host for this currently.
