This behavior in Flow is modeled on how regular Mediawiki page deletion works now. See this screenshot of English Wikipedia's recent changes: http://imgur.com/LwZyEpj. The last entry is a page deletion action, and you can see the title of the page even as a logged out user – so if the title were spam, you'd be seeing spam in recent changes/contributions as a non-admin.

Of course, it doesn't *have* to work like this - but we've found that when we try to show things different in rc/contribs/etc., people complain that it doesn't work as expected :)

Not quite. In your screenshot, we can't see who edited the page that was deleted, nor any of their edit summaries.

Longer explanation:
In regular MediaWiki page deletions, the individual page edits are removed from public view, and only the final page-deletion action is visible to all.

eg. http://i.imgur.com/ivZVvRI.png - Here, #1) User:Derklion makes 2 edits to a page, then in #2) User:Quiddity deletes that page, which removes Derklion's contributions entirely from public view (both RC and Contribs), and places them into the "Deleted user contributions" feed.

See http://i.imgur.com/QzLAC2t.png for #1) Derklion edits #2) Quiddity deletes the page which hides those edits #3) those 2 edits are now only visible in "deleted user contributions".

(Hopefully that's explained clearly. And our apologies for the imgur links, to those that hate them ;)

Quiddity - right, that's why I said "modeled on," not "identical to" ;)

Flow actions are fundamentally different from page edit actions, so they come with extra meta-data that may or may not contain inappropriate material. However, my point stands that if the root issue here is "I think it's bad that some non-admins might see spam/inappropriate words/etc. in contribs or recent changes," then that's no different from the current system today, because deleted page titles can include spam, personal attacks, etc., and are visible to users without admin rights.

Anyway, since we're moving to a more granular revdel-like system of deletion and suppression in the next sprint, I trust the local admins to make the call whether a Flow action and its associated meta-data needs to be deleted or deleted & suppressed.
