Block, not ban, but that sounds like exactly what you’re looking for. If seeing these comics is that big a deal to you, you can block everyone who posts them and eventually you’ll almost never see them. The only alternative I can think of is just putting up with seeing things you don’t like, which is what I do and it seems to work pretty well. Occasionally I even start to like things I didn’t like before. But based on the conversation downthread that doesn’t seem like a viable path for you so I thought I’d offer an alternative.
