I think we need to work with the mods to self-police going down rabbit holes. We cannot expect the volunteer mods to do everything for us.
If you see someone has already refuted a troll, resist the temptation to slam dunk on them again in this thread. If you really need to reply again, take it to another thread. And if they try and bait you into replying, just dislike it and move on. Topics that frequently cause rabbit holes already have their own dedicated threads. Unless there is breaking news about it that effects long-term investment theses, start the conversation in that thread.
If it's egregious misinformation, the dislike button is acceptable. It shows others that the post is disreputable without cluttering the thread.
