Yes, the block theory is certainly valid, but I've been dealing with dnc trolls for years prior to this board and have become a believer in mocking them relentlessly. They will spam and troll regardless if you respond, so I found sport in just clarifying their stupidity. Guilty pleasure, I guess.A very large part of the "purpose" is to simply disrupt genuine conversation, which is why you should ignore them... all of them.
Ignore them not just because their posts are bereft of actual substance, nonsensical "points" unworthy of being addressed seriously, but because by engaging them you are giving them what they want.
