You can't have it both ways. If you really honestly think franky1 is a troll, the best way to defeat him is to not engage him. If you want to argue with him, that's fine, but you gotta take some responsibility for the ensuing chaos. This is even more jarring in a thread like this where LN discussion should be off topic.
Trust me, I've fed many a troll over the years. Never led to anything positive.
You can and should ignore trolls but you can't and shouldn't ignore misinformation because it is misleading anyone who would come upon said posts.
For example misinformation is the only reason why even today there are people who think signatures in a SegWit transaction are "removed" from the blockchain! Or for more than a year people were scared of using the new SegWit addresses since someone kept repeating a buzzword called "anyone-can-spend".
