Earlier quoted context omitted.
Many banks have very strict IT policies on posting things on internet, and they have valid business reasons for that. Not saying you meant that, but it's not like they're some dark, silly workplaces that people should get away from asap.
No, the reasons for the policy might be sound. The enforcement is stupid (both the previous hack and now the block). For me this actually would be a sign that the workplace isn't quite the right fit for me, if the basic assumption is that I ignore the policies anyway - because that's what this seems to indicate?
Hack indeed. Seems like blocking POST would block posting stuff while blocking to log in allows you to just copy your cookie, and doesn't allow you to view your notifications.
