Discuss. Not mentioning competitors name, but a multilayer system of captchas, payment cards and addresses is a straight forward enough system to implement. As is demonstrated by the UK shop that shall not be named. Of course, with it being all on its own it can't save the world the UK gamers, but - judging by the threads in this forum - it's outlet is still the best way of gettign a GPU for the ordinary folk.
The algorithm is trivial to implement:
import blacklist #contains previous buyers info, non-UK bank cards, etc
1. Click on the listing leads to captcha
2. IF solved captcha DO: record buyer's IP, billing address, name, card number, linked forum acc, etc
3. IF the above info NOT on the blacklist- DO: sell the gpu AND add details to the backlist
4. ELSE: print "enjoy your previously bought gpu"
I mean really, the scalper problem is not just down to mining - just look at the PS5 fiasco. And thus, it is bound to happen again and again, and again - because easy automation, bots, social media market places, ebay, and other such 21st century stuff. And each time, we'll just say "Oh dear, this never happened and here it is again" ?
IMO the anti-scalper directive should come from the vendors like Nvidia/AMD, but retailers could also win a lot of consumer good will by being proactive. Us consumers may also help - by pushing these concrete proposals to the vendors/retailers instead of fuming into the ether about the market forces and profiteering.
