...cont’d: but i am seriously considering pausing my account until congress can get its act together and pay attention to the tech tyranny problem we are having. i don’t actually think i would be missed on this platform anyway. 
Someone probably was just shocked at the image you mentioned and reported it.
If @twitter reviewed it and agreed that it was a shocking image, they probably just tagged your account's images and videos as potentially controversial + so make people click once to view your media.
