Fred: Theoretically everything that has been posted online can be deleted
Fred: But Internet doesn't forget :D
George: On the one hand I admire your speed at downloading embarassing content
George: On the other hand I really don't get it why are you doing this xD
Fred: It's simple. When someone is a hypocrite and sometimes proves it with posting such content. I feel obliged to reveal his hypocrisy or ignorance.
Fred: Take this politician. The print screen I sent you was a photo of his public post about coal miners 5 years ago.
Fred: <file_photo> This one is from today.
George: He contradicts himself.
Fred: Exactly. Because he says exactly what he thinks would bring him support. But as Internet does not forget that few years ago he wanted to close the mines, he has less chance that someone would believe him and trust him. 
Fred: And trustworthy politician is a winning politician.
George: Ok. I get it. Still idk why you engage in this, and at this point I'm afraid to ask :P
Fred gathers proof of politicians' hypocrisy on the Internet. George questions why Fred does it.
