I put Fedia.io through this last week. I run @FloatingIsFun which I think is the first active art subreddit on Kbin. I've been working on reposting all 400+ posts from the old /r/FloatingIsFun subreddit. For a couple days, my posts got popular and I really spammed up people's home pages with floaty stuff. It even spread outside Fedia onto other Kbin and Lemmy instances. I felt kinda bad, but I'm glad I got some exposure. The hype subsided after a couple days and things are healthy again.
I'm just glad I'm not alone and there's some functioning art sublemmies now. Keep up the good work! I hope other subreddits follow us to the Fediverse.
