Forgive me if this is a stupid question but if you’re unable to remove apps from the store how will you handle blatant issues of spam or, worse, viruses?

Current plan is to support opt-in moderation. Users can subscribe to banlists or curated lists (which could be machine generated) which filter content.

If a user doesn't like their moderation/filter, they can swap in a different one or disable it altogether.

Wow interesting idea. I am probably way behind you on the thought process, but my first thought is: I wonder if you are just shifting the meta game and adding an extra step for those wishing to push malware etc. They would need to become list curators and promote some percent of legitimately good apps while also pushing their bad apps.
