Anonymous participant what you are talking about? Legal Banking? Dtv not allows you to work! It's a tourist visa! There is no permission or work permit for online working what is clear because it can't exist. Never ever anyone got a problem since Internet exist in Thailand. There is no law what you can break. If you don't know anything about law then don't post anything.
of course legally, it was never illegal. When does the last moron understand that dtv is only a long term tourist visa. Nothing to do with work. You are not working in Thailand by law if you are not working for Thai clients.
Another troll post, why it's allowed to post anonymous, it's not a question the poster ask it's a lie! Imigration officers ask random people even normal tourists questions, to find out if there is something to worry. And this all imigration officers in all country do. Why can anonymous people trough in wrong facts? Especially here when 99% of the members do not have any clue about Thailand and how it's working here in the country.
