This is similar to Stackoverflow's 'Technologies I don't like' resume section. Every time I encounter something truly horrible I add it there. I also add tech to filter out roles I'd rather not get tricked into doing. So far I get asked about this section a lot. Mostly from recruiters curious to see how flexible I am because internally the company does a little X or Y and needs to know if it's a deal breaker. It can really tell you a lot about places you would rather not work at though if you know for sure there are processes you want to avoid.
