I suggest Twine is posting fake jobs and emailing users non-existent job opportunities. This may not be true for all posts but I feel the two I looked into were not legitimate opportunities.
It may be legit, I do not believe so. Let me know if you have experience with Twine.
I emailed Codexite, if they respond I will add a comment. I feel like Codexite is just one dude making videos out there based on the FB profile and his website. He has no clue there is a job posted with his business name attached to it. The article I came across is basic SEO content.
