I was working for a scientific journal. In the peer-review department, they had to use this proprietary software, and we had 2 employees who just mindlessly went through this proprietary software's form day-in, day-out. This form spammed scientists for reviews of science articles for our somewhat-predatory journal (we solicited authors to publish in our journal for a fee)...

First, it was a massive waste of those 2 human's intellect, entering data over and over into a generic form from a proprietary business' website, in order to spam scientists. I started a ruby project to automate out all those processes, just using selenium to enter the data onto the web form for us. Before I could get very far, I got a huge promotion elsewhere and left that under-compensating journal.

It all gave me a depressing vibe though, both the ethics of what we were doing and the waste of time/life that those employees had to endure to do it.
