From the first 3 words in your post I thought it could be the throat perv.
And yes, it's him. See http://www.eslteachersboard.com/cgi-bin/forum/index.pl?noframes;read=109432
See the whole thread, started in 2006.
Do not talk to him.
This evening I got a call from a private number. The man told me that he was looking to fill in a teaching position in a school in Korea. He hardly asked me any questions and was only interested in ehether or not I would be able to Skype with him as soon as possible.
He introduced himself as Dr Stillman, no first name and nothing about what school or organisation he was working with. His Skype handle is Stillman121. I'm supposed to call him tomorrow at the same time only because I'd stopped using Skype ages ago and didn't have a working handle.
I'm very suspicious of how little information he gave and how little he asked for. I obviously couldn find anything on him except two previous scam warning on this forum in 2016. Has anyone heard of him? I think it might be the same guy.
I might still do the interview tomorrow but I will proceed with extreme caution.
