Membership history

Growth

Growth history is still building. We hold one measurement for this entry. A trend needs at least two, taken days apart — so this will fill in on its own rather than being estimated. We do not publish numbers we have not measured.

Ownership

No owner on the last measurement — this group is ownerless as Roblox reports it. Ownerless groups can be claimed from inside Roblox by an eligible member.

Groups seen changing owner — the largest ever handed over and the most recent — are on the ownership transfers board.
