Interesting. I can't search and find @BBCRD on my Akkoma server to enable a follow. Now wondering if this relates to the unique top-level domain.
It will likely sort itself out over the next few days, but it was unexpected to not find the account...
This has now been fixed. Thank you @FloatingGhost !
