I find it (slightly) amusing how Facebook, Instagram LINE & consort assault us with more and more advertisement but are kind enough to allow us to 'hide' those we do not wish to see by offering a very politically correct American way to 'express' our opinion: not relevant / see it to often / find it offensive, so it can help them to find more suitable advertisement to invade our space, privacy and mind - and to make a paraphrase of that famous phrase, "I want (more) therefore I am"...
