schools making idiotic decisions (school computers edition)

i kinda understand blocking vpns, but why the FUCK did my school block pop-up/ad-blockers?? children use these computers, and they can easily stumble upon websites that have porn ads + pop-ups and could even click on a pop-up that could give the computer a virus... i've been waiting to rank about this so i probably will tmrw since this is something that has bothered me for a while tbh
