What started out as a nice little game, encouraging imaginative play and age-appropriate social interaction that gave everyone a chance to fully participate has been destroyed by capitalism, dark patterns, and perverts. We can do better. We know how to make nice things, we just need to learn how to defend them.
When you talk about the anonymous people on the internet, everyone is a perv. Roblox spends a ton of money each year trying to make the 70+ Million and growing daily active users "civil" to each other, but I hang out in the Discords with these people, and it's clear that nobody is watching the next generation, teaching them manners or even spelling when interacting with others on the internet. Otherwise Discord servers for very popular Roblox games wouldn't have squeaking voices join the voice chat, scream the "hard R" and leave. If you don't know what that is, look it up in an incognito window.
Tix was an interesting currency, but the moment you could buy Robux with it, people botted the platform to obtain it. Censoring people down to being able to talk with emojis like a twitch feature is a cool idea, except then people will just hang out on Discord instead. Largely, that's what people do anyway, ignoring Discord's 13+ year old requirement.
I understand your complaints. You can't put the genie back in the bottle and go back to 2013, when Roblox wasn't popular, had a handful of mostly teenage users who were mostly building simple games and cooperating, and the internet was a much slower place. Parents and other adults and teenagers with malice, including scammers from around the world joined in the games. Roblox went public and now that it is public, it is on the road to profits, and that involves biggering (reference to the Lorax). Go buy some Thneeds!
