Still waiting for some feedback or help on this issue. Gotosocial is gaining in popularity and I know of some others including myself who cannot follow their write.as blog on the platform. You can find the profile but it is marked as private. Clicking ‘follow’ results in a request that can’t be accepted.
I did some playing around and found that I can follow blogs on writefreely instances but not write.as… I still get that “requested” when I follow anything that is hosted on write.as.
