I don’t even need to spend money on it because I get all my robux by selling paintings in this one donation game on Roblox LOL
If you’re good enough at pixel art you can get crazy amounts of robux on there. I was once selling a painting of a candle for dirt cheap (5 robux or something like that) and some guy came up and said to change the price to 100 robux and then let him buy it. He actually did it.
The only problem is if someone on that donation game is crazy enough to spend money to get enough robux to afford your art. But most of the robux in that game was bought regardless of your art because nobody’s crazy enough to pay real money for a piece of art they can only view inside of a roblox game. They can’t take it out to see it elsewhere unless they screenshot it, but they don’t even need to buy it to take screenshots sooo…
Overall, getting robux by selling art in donation games is the most ethical way.
