Knight of Britannia
I just imagine that if I were someone who had that kind of money, but knowing the environment on the site... I don't think I would admit it. Bragging rights is one thing, but a lot of people look down on those who'd spend that much on something that's not even tangible. It would maybe even open them up for hackers/scammers... That would be my fear, anyway. I know there are people who've bought some seriously pricey things on here and lived to tell about it, but 20 grand is way out there, haha.
I'd be fine with it if they like saved a ton of their money for 4-5 years or so and had 20k or more. They at least SAVED money and wanted to use it to support their favorite site. This would assume they still have money to pay bills, get food, etc.
I know people gripe about others who'd spend any amount like $50-$100 on pixels, but as long as they like what they got..it's whatever IMO.
