Looks like KBin has an edge over Lemmy now in terms of monthly active users.
It's obviously a pretty silly thing, and is not in any way indicative of which project is "better" or more "long-term viable" or anything — instances of both federate with one another, and with the rest of fedi, so it's all one happy family.
That said, it's notable. KBin is a relative newcomer to the "Reddit-like fedi instance" game, and also does not have the tankie baggage.
Anyway, the more, the merrier!

I believe there was a post by a Kbin hoster that they had to set up a specifc rule in Cloudflare to get around the issue. Although AFAIK I would assume that Cloudflare could definitely be causing some issues for some instances which may not be set up correctly to get around the issue, which in turn could lead to the issue your suggesting. But then again don't quote me on any of this I'm not a dev for any of the projects, and I'm basing this on my own projects where getting around Cloudflare to scrap data is a complete pain and sometimes more work then it's worth.
