Well the Roblox community I’m currently in right now, all of them are friendly. None of them or ODers or slenders. Yes, there may be some toxics from time to time but they usually go away. And the devs of those games were constantly making balanced updates. The games they have are really fun for me but it may not be fit for everyone, as it’s mostly strategic and competitive. I’ve encountered 2 communities that are perfect:
The Blox Cards Community
Ballista Community
Yes, I’m pretty sure you have never heard of these games at all, but that is the exact reason why the community is clean. These games, highest I’ve seen, only have 100 people playing max. The community even states that they have absolutely no interest to became popular. The best part, the games are light years away from pay to win and they are perfectly countering metas in the game by either nerfing or making/changing a thing to counter it. Roblox games that are popular are usually filthy with ODers, slenders, kids and toxics therefore forming the “Roblox bias”.
I’m pretty sure I won’t get a low rated comment because I stated a reason sensibly and I will not rage like an immature 5 year old.
TL;DR My community is clean and fun because it’s not popular. Popular games’ community are usually shit because it gets interest of many players, including bad ones.
