Yeah. There's several posters that are notorious for the "it's up to you to substantiate my claim" laziness.
Part trolling, part willful disinformation (IMHO), but it adds up to (thankfully) them being identified as using that practice and being challenged by more and more FReepers.
Or just as frustrating is when going down the rabbit hole you hit a fork. When clarification is requested as to which fork to take, they go vague or nasty and say your not doing the necessary work. The bottom line is they don’t want to get you to proof. They want you to find something that resonates with you and sucks you in.
