The rash of mysterious error messages recently encountered on Meta-owned services when attempting to post fediverse links would seem to be erratic. Some links work and others produce the error. So far, We've seen reports of errors with links to the instances mas.to, tech.lgbt, and musicians.today.
There would seem to be no pattern. mas.to has 19k active users, musicians.today has 164. But there is one commonality: All three are part of the FediPact.
Moreover, the https://fedipact.online site provides a one-stop shop for a FediPact-based blocklist, so implementing such a thing would be a snap.
Folks with accounts on networks owned by the Zuckerberg entity can help to confirm the hypothesis by attempting to post any link to any FediPact instance. Let us know! cc: @FediPact
