Noticed he posted using 19 mm marine grade, so where did I miss the 12 mm flex?

Curious why he abruptly stopped posting after leaving us hanging.......... The site indicated I was signed in, though don't recall ever joining or seeing this build, so added a comment, appeared to accept it, but then didn't show it and removed the 'comment' section on all pages even after leaving the site and opening in a new tab! Hope it's not a scam/whatever site.
