yes, this is what I figured out over time too, their game is keep your eyes on their app any cost, that's why they can't be totally transparent or do things that would actually kill the bot activity pretty quickly, they need to appear to be doing the right thing but not actually doing it.  

 that and their share value would plummet (well, not X's anymore), if people learned how many users are actually just bots 

 i'd put the number of bots and paid agitators at 60%+ of active accounts
