Can you copy/paste the article? I'm not a member of Dave's but I am interested in reading it. I've googled "ESL teacher child molestation Korea" but only have come up with blogs briefly speaking about it. One case in Daegu involving a teacher (no nationality listed) in his 50s and 2 6th grade boys (2010) and another case in Seoul with a Canadian teacher in his 40s and 3 1st grade girls (2009). Both are horrible, but don't mention them being accused/spending time in jail/paying financial retribution for the offenses.
Something like this would be all over the newspapers, but I haven't found one case to be published in any of them. If it's speculation, then I only see it being written to sensationalize and sully the reputation of foreign English teachers in Korea. Any schmuck can write his opinion in a blog, but reputable newspapers would (or I ought to say 'should') report the facts.
If you can't find the news article, that might be because it doesn't exist in English or doesn't exist yet. Even though I pity the fool who is accused of molestation, it's jus' a whole lotta unverified jibbajabba. Be really careful of what you post because Koreans are ultra-savvy with the cyber world and something like this could flood the nation with torrents of foreigner-bashing drool and not many Koreans can tread water...
