It most certainly is illegal and people have been arrested for doing business and also selling things online whilst in Thailand. I am sure a lot of people run online businesses from Thailand with no work permit, but that is their choice to assume that risk.
I have been professionally dressed and harrassed by female IOs....but yes when I fly business class (sadly not all the time) there are never issues......If I could get a long term visa I would...but there are no affordable provisions for under 50s....already had ED visas......Anyways now have a kid, I will follow that route....if no kids, not married, under 50, do not want to pay for Elite, etc.....you are screwed...
555 Robert. Plenty of men though. I am talking about at the airport specifically. I started going to only men about 2 years ago and have had no problems since. The few years before that I had problems on a number of occasions with the female IOs, ONLY females, never males. It does not seem to be a coincidence. Look at most of the posts when people say they had problems. 99% always start the story with SHE.....it is my new system and it is working so far :)
