Group owner’s getting banned on ROBLOX and the groups owned by them becoming forever locked has been a issue for many years. There really should be a feature where in the case a owner is banned the group should be immediately set to unowned and be able to be claimed by anyone, or have a designated backup account added to the groups ownerships.
This may have it’s pro’s and con’s but in all honesty, it allows for the reuse of groups and not the creation of another one trying to use invisible characters.
