Seems to me what you want is a way to indicate that something is
technical and then very end user oriented things like activity stream
should not show them. Not sure what is the best naming for it but at
least I think "Hidden" event
would be more consistent with hidden documents which is used for more
or less the same thing ("technical stuff probably most people don't
care about by default").

The problem is that "ignore" seems to
be more obvious for you that it
is in reality. What you call "completely ignore" is actually ignore it
in things like auto watchlist and activity stream but you certainly
don't want solr, clustering or right system to ignore those.
That would work. If some listener doesn’t want to ignore some events (because it *has* to
support them for things to work fine) then it would not ignore them. But the semantics
would remain that they should be ignored *whenever* possible.
Note that there are probably not that many use cases where we really want to ignore some
events (since after all in a wiki everything should be tracked) but I think those use
cases exist. It could be argued that even in the case of Spam cleaning we would want an
entry in the AS that would say “Spam cleaning executed”. However when the AS implements
the ability to see nested events, they should not be shown in this case (they should be
ignored).
