CFC: Erratum for Section 5.3 "Followers Collection"

This is a call for consensus to add an erratum for ActivityPub, to 
correct one of the problems reported in issue #320.

https://github.com/w3c/activitypub/issues/320

The text of the erratum is as follows:

    Section 5.3 "Followers Collection" erroneously says that the
    "followers" collection is ''a list of '''everyone''' who has sent a
    Follow activity for the actor'' (emphasis added). Because the
    receiving actor can optionally Reject a Follow activity, the sending
    actor can later Undo a Follow activity, and one or both could Block
    the other, not everyone who sends a Follow activity will be in the
    list of followers. A possible correction is to replace the text with
    ''Every actor SHOULD have a followers collection. This is where one
    would find a list of all the actors that are following the actor.''

If there are no objections to this addition within 14 calendar days, I 
will add this erratum to the ActivityPub errata list and apply the 
correction to the editor's draft.

Another error is reported in the same issue, for section 7.5; this has 
already been through the CFC process and applied to the editor's draft.

Thanks for your attention!
