Once, many moons ago, a group of devs at my old work got deny on internal zone-to-zone Firewall open request that they needed for integration between two internal systems, so they ended up making a script that e-mailed the info to a hotmail.com (SMTP was open) account and then wrote a script to login and screenscrape the mail info from hotmail back to the other server (https was open through surf proxy).

My employer blocks adblock.

I no longer waste time.

Because i have already broken all the company security policies.

Protip: convince the IT team that Linux is essential for your development work. Small percentage of the IT team is aware about security on Linux.

My company once blocked access to its own website.
