I hate these topics, so I'm just gonna say this now:
Yes. It's a free to play game. Yes, it has a lot of money options. How do you think that makes them money? And the community's bad side can be bypassed when you find the right people, or just make your own stuff.
ROBLOX is fun if you make it fun, and it's bad if you make it bad.
That's all I'm gonna say.
