No.
That idea, let alone that attitude, is not conducive to a place literally designed for discussion of game related topics. There is a difference between in game chat and a literal public forum built for the discussion of ideas.
Regardless of if you like or dislike what someone says, simply removing all traces of their presence to create an echo chamber where only you can see what you want to see does not benefit the greater discussion as a whole.
The forums are someplace you willingly come and exist as a place to share feedback and ideas. They are not your personal club house or safe space.
If a person is being harassed, actually harassed and not just upset someone is saying something they don’t like, then use the report feature. However, at the end of the day this is a place of discussion and idea sharing and cutting out discussion through an ignore feature does not belong here. If you want an echo chamber of agreement the join a community, discord, or guild with those are views.
