I know the topic of 'thread jacking' has been discussed before. If you feel someone is thread jacking your thread, how could we block or hide them from a thread? I haven't had the need for it, but have seen borderline instances.
Also, is there a discrete way of taking care of thread jacking situation without causing drama on the thread? Not sure if this is possible.
ETA: I'm talking about negative thread jacking where it can completely derail the thread and turn it into a possible heated thread.
