Your warning was for cursing and using excessive language. Including every kind of genitalia, asking people to kill themselves and so on.
A few months ago you posted straight up porn. That gave you another warning.
One of the sites that weren't blocked on the school's network was some file uploading sites. I would upload some games, write down the URL and take it to school one day.
my school has a chrome extension called light speed filter agent and it legit blocks YouTube pfps since the file cdn(I think aka yt3.ggpht.com) is classed as mature
It was easy to bypass some of the restrictions, as one of the admins left a registry key in the administrative shares drive, which allowed me to get around the blocking of some sites.
