It is worth noting that in PH, using Facebook is free but every other news source uses up a very small data cap. Few can afford to pay for data so everyone is totally hooked on Facebook. Also labor costs are low so buying a "troll army" to flood the zone is extremely cheap. Combine that with a very low level of education and it's just echo chambers of insanity everywhere.

There are striking similarities between the first Duterte campaign and Trump's 2016 campaign.
