Yeah would be interesting to see.
While we do have some activities in that sector, mainly @lovesniper where curators curate good first posts they find, recommend them communities they may be interested in based on their posts then give them a follow to check their future activities (people can check @lovesniper/feed to follow it themselves), and then we also have our own onboarding program which people can follow on the @ocdb compilation posts that have a very high retention rate. It would still be interesting to see overall numbers. I am seeing quite nice retention and curation in general and referral links working somewhat properly through beneficiaries being sent to onboarders in different ways (either through peakd sign ups or through hiveonboard directly - not our onboarding program).
There are only a few questionable accounts doing some questionable curation, nothing too big or too much stake and when it gets out of hand it is nothing that downvotes can't fix or adjust.
