So I am a part of a wonderful big realm full of amazing people, but this one guy got banned, then made an alt, and has now leaked the realm code to a ton of communities, I reported his posts, Asked the members to halt inviting people, and as a last resort I have tons of defensive measures, but is there anything else I can do?

Bedrock realms btw

Edit: we have already changed the realm code
And I have also reported his posts
