The same thing just happened to me, except they contacted me DIRECTLY! Through ESL 101, operated by the owner of Footprints Recruiting (a legit recruiter). I looked online, thinking it was a scam hagwon, but turned out to be a legit school with U.S. articles written about it! I thought ok, it actually IS legit, so I went ahead and filled out their information. I just received an acceptance letter from them as well, but before signing anything, I had a list of questions, including if I could see an ACTUAL CONTRACT. They haven't responded yet, but I am wondering what they get out this if they are not asking for any money? Strange, strange...
