I'm ok with 2-3 freebies, it actually incentivises newbies to experience SN for free and migh give the opportunity to get some sats or ccs. But bringing that into debt, is just too much, and we know from experience debt can only grow and never be paid back.
If you limit that leverage to 1 post, you can terminate the "uncooperative" path in the prisoner's dilemma.
