Thanks for the feedback. The Search API for HN is provided by Algolia. The action bar is of course hidden when scrolled. Noted down to add the pull to refresh function.
WhatsApp hasn't even updated their TOS in their site since 2012 and moreover Facebook can disable account only if someone "infringe other people's intellectual property rights" inside FB. This makes me wonder what made it in the first place to allow FB disable account for violating WhatsApp terms.
Are you saying Facebook don't have a term in their ToCs equivalent to "Facebook reserves the right to stop service or remove data for any or no reason at any time without any notice"?
