I get where you're coming from but I think this ban is based around intent. While Roblox is definitely an evil ass company, their ultimate goal is to make entertaining games and make money off purchases in those games. Also, they've already implemented ID checks for voice chat and even then it's quite heavily moderated.
The ultimate goal of social media is simply addiction, data harvesting, and selling that data to everyone who'll pay for it.
That is pretty lame tbh.
