Unfortunately the possibility of this not being stopped exists, so I wanted to give you some feedback of what to do to help preservation. Given these places exist and are still filmable, consider recording these places or have someone who’s competent in doing such create film archives of these places. Although Roblox allows 2 videos per client, it shouldn’t be hard to showcase these videos through a Roblox place or online. I’ve done a lot of streams and recordings for the old Roblox Clans & Guilds genre over the years and have been a goto for many big and small groups for producing their media.
If you need any help or want more feedback, feel free to add me on Roblox. Wish you well in your archival efforts. It’s special for so many people who want to come back to it I’ve learned over the years, and worth something.
