#1. IP limiter #2. Heat Map #3. Limit number of battles you can play each day #4. Hidden invisible recaptcha (no one would see it) #5. Honeypot trap. #6. VPN blocker. These are just a few methods that would easily stop 99% of bots lol.
So if I invest in a VPN service I'm out?
Also, some mobile internet networks popular in various global regions give new IP addresses every time they connect.
There's a tonne of services and games that aren't crypto related that you can't access from a VPN for their own security purposes. You can turn it off to play splinterlands unless you're some tin foil hat wearer that thinks splinterlands team will be tracking your toilet habits because they can see your ip lol!!!
I've never seen it that way, but it sounds draconian.
