As you correctly wrote, Ian Patrick Leahy is the one-man-show owner behind ESLinsider. He has a long criminal history, including the reckless act of recommending his graduates without college degrees to purchase fake ones from him. Because of this, several TEFL students were detained in China and later deported.

It’s also widely known that Ian has been banned from Facebook since 2017 for spreading false information on the platform.

His main form of course advertising involves writing disinformation articles about his competitors—portraying himself as a reliable provider while labeling them as scams—and then deceiving his own students.

The last I heard through the TEFL grapevine, Ian was traveling around the United States (living a van life) and continuing to scam the few new students who unfortunately fall for his misinformation.

ESLinsider is a bottom-of-the-barrel online TEFL program with a terrible worldwide reputation. I strongly recommend that everyone avoid his course and any employment offers associated with him.
