So in the last few days I have clicked on a couple of dodgy links. 

One was an interracial porn video someone i know apparently shared, the next day i saw someone else i know apparently share it. o im thinking when people click on it it automatically shares it and the account owner can't see the activity on there page only everyone else can. 

I clicked on it out of curiosity i do not have friends that constantly share porn.

Then I saw someone else giving big long links to a life meaning type / words of wisdom type image. Maybe genuine may not be. I clicked on the link and was taken to the image. I thought the person who wrote it to the other person was a weird situation, do they even know each other? then scrolled down and saw the did a similar thing to someone else. 

It may be legit, and people pranking by liking the interacial porn link, but i am worried there is stuff my account is posting that i can't see
