My school has their priorities straight! (Not)

Trying to do some project about the Stock Market in my Next Gen Finance class, and when I tried to go to Yahoo Finance, since it's always worked for me, my schopl decided to randomly block the site for no apperent reason and I have no idea why they decided to do it.

Asked my teacher for help, and thanks to him being a bit of a geek about the Stock Market, we found an alternative in Google Finance that thankfully works.

Why does my school block sites like these, but DON'T block sites such as Roblox, sites that are known to have content that is inapporpiate for school, and can prove to be super distracting to students :/
