As much as your intentions are good, they won't work. People with this mindset are never dissuaded by pesky little things like "facts" when said facts disagree with their "beliefs."
These two will continue to avoid any reputable grading services and instead, seek out harmless allies like the "printing expert" who can't spell the names of the schools he attended, and "antiques dealers" who sell Beanie Babies.
What would they gain by taking you up on their offer? Their little life excitement would be over.
