The American movie star Leonardo DiCaprio has more than 61 million followers on Instagram.

So when in July he posted calling for the protection of a nature reserve in the Philippines it made

headline news.

The Philippine media like state-owned PTV eagerly covered the story.

It wasn't just that Leo was mentioning the Philippines on his socials.

It was also the fact that he was accusing the government's environment

department of putting this nature reserve at risk, which they denied thanking him for his

concern. Meanwhile on Facebook news outlets boasted about the story too and readers

made their feelings known in the Commons area. Some of them didn't seem quite

happy with the actor's intervention.

Don't be a loser, Leonardo.

Does Lee you know what's the real story behind the issue?

But there was something unusual about these comments.

They were posted by accounts with very few friends, accounts that seem to have very little interest in anything that wasn't, well, related to the environment department, which made me wonder, could there be more to them than Matt D.I.

All of these are very consistent with what I've seen before previously while monitoring troll farm

activity.

Internet trolls? Really? But working for whom and to do what exactly? Getting those answers was not going to be easy.

This story starts at the Masungigigo Reserve, an area covered in lush rainforest to the east of Manila, the capital of the Philippines.

And it's there you'll find two sisters, Anne and Billy Dumall Yang.
