Some onboarding abuse?

Dear All,
there is a new post curation tool, developed by Hive account@ecoinstant and Hive account@thecrazygm and just featured by Hive account@friendlymoose here which is really nice (and NOT funded by the DHF). The search function on Hive is notoriously bad has still potential to improve, so any initiative in this regard should be appreciated (hence the beneficiaries of this post)! Here is the link:

If you search for the tag #checkin you will find a ton of semi-automatically generated posts (rather oneliners with a pic):

Those "posts" (often with a welcome message by the diligent Hive account@godfish) get rewarded app. 5 to 7 HBD which is less than decent introductory posts (made visible using the tag #introduceyourself) but also the effort is zero. In addition they often get 2 HBD from Hive account@threespeakselfie sent directly into their wallets and even some sats from Hive account@v4vapp. I think this is not too bad as an incentive for newbies.

With so many new accounts constantly generated I am wondering why the post number and the number of active accounts as regularly shown by Hive account@dalz and Hive account@arcange are stagnant and not moving up!

I randomly checked 3 accounts created a few days ago for some follow up posts, one of them is here:

I checked the wallet and the 2HBD gift plus some discount from Hive account@thedistriator was one day later already swapped to Hive and sent to another account! Turns out that other user which is on Hive since 4 years resembles surprisingly exactly the "newly onboarded" user!

So why needs a user active since 4 years get "onboarded"?

Maybe does the monetary incentivization lure people into abuse for some quick dollars?

As said, the sample was very low (I am sure there are ways to check this automatically) but the quick find after 3 checks at least warrants some further research into this. Fake newbies steal from the reward pool, so the question is, if it is the right way to immediately gratify people for making a pic or if some rewards are paid out only after a more lengthy follow up post?

I have no solution, but I think it is worth a discussion! There will always be abuse but the question is (and we need more solid data for this) if we should accept the abuse because we think a reasonable share of the new users are real contributors or if we are again wasting money here with limited benefit...
