A community is not relevant to the statement of the problem, but a community is relevant to the collective action problem of adopting a solution (depending on the solution). I agree that the opening sentence about sending “an email to someone in rationality” is unhealthy and condemn it with you.
But, as others said, Jacob is right to talk of “a coordination campaign to move the community” and at some point he has to name the community. (There are additional issues of whether the community exists and whether its existence or name is bad. Those are hobbyhorses.)
