Roblox is a massively multiplayer online game platform that allows users to create their own games and play games created by others. With such a large and active community, it’s inevitable that there will be times when you may encounter someone who you no longer wish to interact with. If this happens, you can block them to prevent them from contacting you or joining your games.
There are a few different ways to tell if someone has blocked you on Roblox. One way is to try sending them a message. If the message fails to send, and you see a message that says “This user cannot receive messages from you,” then you have likely been blocked.
