Hello AmaaDivine, I appreciate your question.
This is a very valid concern, and one that we have been working at for many years. Some of the features already built into the game involve the Chat Filter, and other internal systems for Moderators to see when issues arise, and handle them. We have a pretty large and dedicated moderation team, and in the rare moments that something has gotten past our systems, they have dealt with it very swiftly. Also, of course, if there is ever a problem you want to notify them of, you can always get in contact with them quickly and easily. No process or system will ever be perfect, but it has served us well time and time again.
Beyond that, while the idea of a separate map/room is intriguing, such is not our intention. Our plan is to have servers for all ages, and that means ensuring that they are always safe for the younger crowd. It has worked for us during all our previous events, and we are confident that it will continue to keep all players safe and comfortable.
To reiterate, if you ever have any sort of concern, on the forum or in the game, and it is not seen to quickly enough for whatever reason, you can always report it to the moderation team. They will remedy any issue as quickly as possible.
I hope I addressed your concerns, and if you have any further questions, please message me!
