But I'm not sure it can be pulled off easily on a site like BPIP the way we had originally intended it. The only other ways I might foresee it working close to what we intended would involve much more development either with account creations/logins, or some sort of walled garden which prevents a direct instant generation of a card from any user (while avoiding a queuing system that will probably be just as abused).
If rate limiting is a problem (not sure if I fully understand the issue at hand, though) - have you considered small Lightning payments for access? As in: very cheap for occasional usage, but too expensive to be able to spam the system?
What exactly are these cards all about? Now I'm intrigued..

I have not updated the original thread in a while, but some general info. and
older samples could be found
here.
I think they look super cool! I'd honestly like to own the physical cards of my favorite Bitcointalk members..

Only issue is that the stats change all the time, no? Would there be certain 'snapshots' in time at which a full set of the whole forum is made (e.g. 1/1/2023 edition, 1/1/2024 edition etc.)? Otherwise it is unfair to compare them (e.g. 2023 LoyceV vs. 2020 o_e_l_e_o).
