Violations notice, can I get in trouble?

For the first time (I noticed anyway) a violation notice. I have saved various pins of art pieces, photography, etc. that contain some nudity. I never knew this was even a problem to Pinterest because I have seen many art works including nudity and various pins that they’re saying include “adult fetishes”. Can my account get removed for these photos I’ve saved? Why is it my fault? They’re beautiful art works and I am being punished for saving items that I didn’t know were violations and that I didn’t even post/publish/create (whatever the word is)! I don’t understand why they even send violations to people who happen to stumble across and save the pins. Why not just ban or send violations to the creators?
