So, I want to ignore questions for certain users from my Questions/Unanswered feed. How do I do that?

The main reason for this kind of feature is that not everything that annoys me is against the rules, and I don't want to punish other people for me getting annoyed at them.

But, if I can't ignore annoying people, I am less likely to contribute at all, because why would I come back to place that annoys me, to do free work?

I have been fairly active in EVE Rookie Help and from that experience I know the ability to focus on the people I feel like helping and ignoring the rest is what helps to maintain my sanity and willingness to help anyone at all.

And on the other hand, I strongly dislike the idea of preventing others helping someone just because I am annoyed by him. This kind of environment leads into people getting banned/downvoted by random just because some higher-up had a bad day. Which is plain wrong.
