How to block roblox? As the title says. My little brother (who is 8) has been playing that game non stop. Its lagging my use of the internet, and doesn't affect him, so I pay the price. We already upgraded our internet to the best one available in my area, but I still lag. The only time I don't lag is when he isn't playing roblox which is around 11 p.m. My parents don't think its nothing wrong, and tells me to stop being selfish, which leads him to laugh at me and talks in a "innocent" sort of way to my parents. So, what can I do? Uninstalling doesn't work, as he keeps redownloading it.
