100% agree, the first time I saw the ro.blox.com domain I thought it was a scam. So I can say first hand that it does look extremely sketchy. Plus it doesn’t even make sense that it exists, it’s not like with YouTube where it shortens the link. Think it should be changed to how YouTube treats sharing links. It gives a shortened version of the link.

So maybe for Roblox they can make it https://roblox.com/[GameID].
An example of this. Before:
