ESLinsider and Ian Leahy Blacklisted Warning!

TEFL/TESOL in Japan scam ESLinsider / ESLinsider review, submitted by Trusted TEFL Reviews.

TEFL/TESOL in Japan scam – Ian Leahy.

We don’t find any pleasure in blacklisting an Online TEFL/TESOL certification school, but ESLinsider/Ian Leahy have now reached that threshold.

ESLinsider is owned and run by Ian Leahy.

Ian Leahy is a US citizen, currently living in Fukuoka, Japan, and he is also currently being investigated by the Chinese authorities for fraud.

A snippet from the (documented) accusation:

‘After some deliberation, we have decided to warn all the foreigners now teaching in China that if you sent an email to or even visited their website more than once over the last 6 months, you will soon be investigated by the Chinese PSB as we recently found out in an unexpected interview we obtained with a veteran Captain who has worked more than 8 years with the PSB in a Tier 1 city of China.’

We are not affiliated with any Online TEFL/TESOL certification course program(s). was started by myself and a bunch of other English teachers, who were fed up with the amount of Online TEFL/TESOL misinformation published online.

If an Online TEFL/TESOL certification course program is ranked high up in the list of certification programs, this means that they have received overwhelmingly positive (verified) customer feedback.

If an Online TEFL/TESOL certification course program is ranked low down in the list of certification programs, this means that they have received overwhelmingly negative (verified) customer feedback.

ESLinsider is currently ranked bottom of the list and has featured in the bottom 5 for the past 9 months.

Instead of being focused on improving the course experience for his customers, Ian Leahy has chosen to lash out at with a barrage of misleading materials that he has published online.

Ian Leahy might sound convincing, he might even appear credible, but he is driven by one desire: the desire to work as little as possible whilst earning as much money as he possibly can in order to fuel his lifestyle.

He has been called out on this behavior before – type ESLinsider Asia Scam or Ian Leahy Asia Scam into Google.

Taking into account all of the above information, ESLinsider will now be listed on with a blacklisted warning. This will go into effect from today.

  1. A wise decision to blacklist this complete fraud. People have been arrested because of this guy Ian Leahy. It’s ironic really that he sells his courses by claiming, ‘It was hard for me so I tried to make it easier and more fun for you’. It must have been hard as hell for him if he thinks getting people arrested in China makes it easier for them !!??!!

  2. Looking at my traffic stats, the ip address belonging to Ian Leahy/ESLinsider has visited 33 times so far today. That is 33 missed opportunities to respond, transparently, regarding the (documented) accusation that Ian Leahy is a wanted criminal in China and is responsible for the arrests of North American citizens – teaching English in China – who were caught working with fake diplomas.

    I also think that it is a little ironic that Ian Leahy likes to present himself as a pursuer of truth, a diamond in the rough, and yet it is Ian Leahy from ESLinsider who is the wolf in sheep’s clothing.

  3. I was going to take the Tefl course through the program Ian Leahy offers (ESLInsider) but then I read the reviews and saw how bitter he is to other Tefl programs. Really, the things he writes online about (mostly) MyTefl and Tefl Online Pro is shocking. Talk about shooting yourself in the foot! I watched his latest YT vid, describing (in unnecessary detail) how he moved back to the US, to live with his parents. Looks like his one trick pony days are over. Thank the heavens I stumbled across this website before I made the grave mistake of sending Ian my money for his course fee. Keep up the good work Trusted Tefl Reviews!
