“ With that said: Sure, why not have something like: a vocabulary item that is a property on Objects (same domain as as:inReplyTo) that is like "replyPreferences": "http://your-vocabulary.com/replyPreferences/NONE". There could even be specific pre-baked policy URLs somewhere for "don't reply to me" or "don't reply with curse words" or "don't reply with images" or "don't reply with r-rated images" language that says clients SHOULD inform potential repliers about these preferences MAY prevent replying if the replyPreferences indicate preferring no replies. language that says that servers SHOULD try to enforce the replyPreferences when receiving replies in the inbox ”
“ The Q&A scenario becomes a bit more complex because there is a natural workflow aspect. ”

DISCUSSION ITEM I author a post, who can reply?
inReplyToPolicy (functional, range: ReplyProfile | ReplyCollection)
Class ReplyProfile is a subPropertyOf Profile
inReplyToPolicy MUST be of `ReplyProfile` which
- may have `startTime` and `endTime`
- MUST have `describes` which may be (ordered by precision)
-- an addressed Actor
-- as:actor only I can reply (the Activity author).
-- as:to matches only “Primary Audience”, Actors specified in `to`.
-- as:audience default behaviour, same as no value at all:
the Actors that represent the total population of entities
for which the object can considered to be relevant.
-- :followUnion matches people who are following me which I am following.
-- as:following matches people I am following.
-- as:followers matches people who are following me.
Anybody who replies must then be an Actor addressed in the audience.
If multiple values allow an Actor to reply, then startTime and endTime are
determined by the order of precision which means e.g.:
as:to is more precise than as:audience.
