I bet there's a way for the sub to ban links from a specific domain, so I'm actually curious why it hasn't been done.  There isn't a current way.  Maybe the mods think it would be too much like what imgur did to them?  I don't care either way. We aren't going to force you to choose a host. I personally use sli.mg but that is because imgur's UI has gone to crap. While sli.mg has improved it's and made it easier to use.
