I do enjoy browsing Bluesky and seeing what people are up to. It’s a much less hostile and dangerous environment than Twitter’s been in my experience.
I care a lot about the well being of the people who follow my work - and about my own too! - so I think it’d be nice if these options were added.
Bluesky does have a slightly different moderation approach to most other social apps (posts are filtered actively, but the post data is owned and controlled by the owner so can’t be taken down fully).
I think this is reconcilable with Roblox’s model - especially if we’re talking about more mature and autonomous people - but I do think you would need to consider moderation. Back when devs lobbied for Discord social links (see Roblox’s prior reservations on Discord here), I don’t think moderation was properly talked about in the community conversation, and as a result it’s caused no end of trouble for Roblox having to deal with the prospect of people using Discord in shady ways.
The people in charge of Bluesky seem very nice and responsive though; someone could reach out to them to ask about how they intend to handle younger users.
