It's my fork of rebased and soapbox. It's focused on stability and compatibility, expanding on a lot of work I did on lotide to improve compatibility there. I've also been focusing a lot on making sure all the pleroma upstream work makes it back, as well as great ideas from other platforms like misskey or mastodon proper.

One of the new features I added was groups support, with a focus on lotide, lemmy, mbin, and piefed, but we've done some friendly testing on many groups platforms including things like peertube. The messages you saw were me finally doing testing across the Internet between different platforms -- lotide, lemmy at hilariouschaos, and here.

I've followed and unfollowed different communities on a lot of group or feed platforms without issues, sent likes or removed likes, and posted comments, but this is the first time I've had those different platforms follow a group hosted on fbxl social, and so there was a lot of noise because lemmy and lotide expect much different things than pleroma/rebased initially provided. It's all activitypub, but the ways it's used are very different between the different platforms, so you have to watch your logs and figure out why something didn't federate.
