No community is just a "good community" every single community will have both good and bad members in it, in this case they most likely mean bad as in young children and Roblox is far more popular than Graal and it has various forums and other sites associated with it, if they want to find a good part of the community they are going to need to go find it besides looking at the basic site/forum sections for it where the kids will mainly be posting in.
