Recently, someone made a fork of Bluesky the instance and made Blacksky.

Got curious if accounts would load in there, and upon testing, they do. But then tested further, and even a local RSS is generated, akin to Mbin and Misskey!

Testing for example one of the parallel accounts of Extra Fabulous (comic series - link), just had to copy the handle over to the Blacksky instance (resulting link), and add /rss at the end the same way one would do with Bluesky (resulting link).

Couldn't find any Blacksky profiles yet to test the opposite, but I'd imagine it'd work unless Bluesky actively tries to block the instance.

But alas, good news for redundancy or if someone prefers one service over the other! =D
