In any case, I don't mean to argue that anyone needs to waste their time on idiots. But ignore isn't a magic fix-all solution either and has in its own way cause a tremendous amount of harm, but sure it saves the poster from wasting their time. It can be easy to forget though that the most readers of many posts over the long run won't be regulars or thread participants, but randos doing research or people that landed in from a search engine.
I understand your point of view, but we shouldn't underestimate the intelligence of the people who read us. IMO, people who are interested enough to come across the topic in question and to read it, will certainly have enough interest in the subject to make their own opinion on the matter, whether there's misinformation / lies, or not.
I hope that in 2024, Internet users know that there are trolls, haters and grumpy people on discussion forums, and that they're able to keep things in balance (sometimes I catch myself being optimistic..).
