Iron, he didn't said to make it free. He said half the price or less. ROBLOX doesn't want to suck your money. You choose a username when you create an account. To change it pay 1000 r$ to support them. Then if, 100 players change username they can DevEx and it's profitable for them.
Now for the OP. No support. If you wanna have fun changing your username just cuz its "cool". ROBLOX has no responsibility. Plus, the system would have to detect the username first so no. |
