Visitors can attract mobs which can attack players and potentially grief

Hi!

In Minecraft Bedrock on Realms, players with the Visitor permission can join a server and although they cannot interact with mobs, those mobs can still chase after the player and hurt them. This could potentially be used by griefers to attract creepers, ghasts, and zombies which can then cause damage to your base and such.

Also, visitors are subject to hunger and damage despite not being able to obtain food at all.
