A fake degree doesn't say anything positive about the fake degree holder. He/she is a cheater, and as Beth has said, it's unfair towards students to allow unqualified "teachers" to deech them.
Instead of sugegsting that SB did not have a legal degree in Linguistics, you should better worry about your own fake degress. When will you go back to Bangkok to buy another one - perhaps a Master degree in faking or even a Doctorate?.....LOL

Well it's a step in the right direction if you consider Beth the foremost English language authority on this forum to such an extent that it supplies the winning blow against me in the fact that she agrees with you. She might however feel that our degreeless hero might be a better option than somebody with your grasp of the English language, albeit you say you are a degree-holder, and I believe that to be true/of sorts. I don't know, you should ask her. I am all for just degree-holding native English speakers only to be FT's. Unfortunately there are not enough of those to go around. In which case we either hirer you or our degreeless heroes....Oh what a difficult choice!
