I know about this question, but the answer does not cover all possible options. For example, I don't know Java, so I would like to ignore questions regarding IDE for Java, all the numerous frameworks, including but no limited to Java-on-Linux etc. For the most part, they will not start with
Java-, so I cannot block them like this
If you decide to introduce this feature, it could a community-managed tree-like structure, where you choose to either block the whole subtree, or drill-down and select some sub-items from it. For my example, it could be tags related to Java-on-Android that I would like to keep, even though the rest of Java is ignored.
