Why is pastebin considered a high risk service


The company I work at uses zscaler to restrict access to certain websites.

Earlier today, I tried to visit pastebin.com, but got the error message in the picture below:

Website blocked. Not allowed to browse SHN-High Risk Services category. You tried to visit:https://pastebin.com/

Trying to google why pastebin is considered a high risk service, I didn’t really find much, except this one blog post which talks about certain hacker groups pasting sensitive data to the site.

This alone doesn’t seem like a very strong reason to block the site, as there should be a multitude of other options for making information public. What am I missing here?
