It's fun because Troia in my language mean ***.

1 million likes on such a lame status? come onnn

In what way is this funny?

So if I basically spend once the same amount of money to an organisation (can`t be more than 100 Euro for normal groceries, probably less) like I have done before and many other people before me I am an Angel on earth?
Bullshit! It`s only a small amount of money and it was only given on one occasion.
Real "Faith in Humanity restored" (what a ***ing meaningless expression anyway, that is much to often used in recent times) would be if someone really dedicates a great amount of time and/or effort as long as it is needed into improving someone else's situation and ideally actually succeeds at that.
That what was described in the post is nonetheless a nice gesture, but not at all that what the poster makes out of it. In fact it is a hypocritical circle jerk that anybody can join just with a simple like.
Much like the pictures showing for example starving children in Africa and the Headline "like this if you are against poverty". You are doing nothing with your like, but at the same time you are feeling better about yourself.

over one million likes?!
