The race to the bottom in ESL is unlikely to be won for some time. While the debate about the quality and validity of online training goes on, we had a spammer on the site recently trying to plug novelty TEFL Certificates.
The last time I looked at a site offering forged certificates, they were charging a hundred dollars, but this lot were offering a batch of no fewer than eight certificates (i-to-i probably) for €100. I have no idea how many people are buying these things, but some must or they wouldn't be around.
I'm not sure how much they add to the debasement of education and qualifications, but the people daft enough to buy them will only be able to get jobs in places that would take them anyway- the schools that are looking for someone with a pulse and will happily rip off people with or without novelty TEFL certificates.
