User blog comment:Brandon Rhea/Fandom and Curse Media are joining forces/@comment-2212553-20190101224628/@comment-26402117-20190105165000

The wikis are gone, and proof of approval is right there on the merged wikis' forums. There probably isn't any statistical data on the wikis, because Special:Statistics isn't working on FANDOM. But a forum is better proof really.

Gamia didn't actually have a community to even ask. I didn't hear any objection from anyone on FANDOM, and Gamepedia admins were impressed. Diep.io was merged with approval from the "other community" (mainly FANDOM users joining "for a laugh") and even from the developer.

Imo, if the admins of the merged wikis genuinely believe the other community is dead, asking for "proof" is a tad counterproductive. You could try contact TwoTailedFox (admin of both gaming "hub"s) & Banarama (admin of both Diep.io Wikis) if you're interested in confirming what Brandon has said.

EDIT: Zmario is/was? an admin at both gaming hubs, so you're welcome to ask them as well.
