compare AP Notification with WebMention

On first sight it looks very similar to http://webmention.org/

Social WG charter lists it as one of possible inputs for Federation Protocol

They're broadly similar concepts, yes.

WebMention just carries the post's URI; AP notification requires that
the whole activity be conveyed. AP notification requires certain actions
on behalf of the receiver (e.g. further distribution), in line with AP
covering a whole social protocol rather than just a subset of it.

WebMention lately adds Vouch extension for automated anti-spam http://indiewebcamp.com/Vouch
Do you have anything addressing this issue? Searching your draft for spam gives no results. I think that unless you can sign the payload, fat push will have security issues and receiving just URI (as webmention does) gives you chance to fetch it yourself.

ActivityPump requires strict validation of payloads outside of the
sending server's domain (i.e. fetching of them by the receiver). I plan
to add that senders SHOULD elide the contents of any such payloads
(substituting the URI of the object in their place, as AS2 permits).
However, there is attractiveness in the "just send the URI" model; I'm
not necessarily opposed to it.

As for spam... its' more difficult in our case than IndieWebCamp's,
because IWC assumes person per domain, etc, and there aren't (presently)
any open registration sites where spammers can setup camp.

I think we may wish to here suggest that implementations accept by
default all messages from the people you follow & the people they
follow, and then perhaps also implement some form of intelligent spam
filtering algorithm (Bayesian or similar) for the rest, with a similar
"spam folder."

We may note that Facebook implements similar logic with its' "Others"
messaging category (except theres no Bayesian algorithm there).

Really, I think the spam filtering method should be up to implementers,
but making suggestions about using "friends of friends" is probably a
good idea.
