Yes, #thai tag is for Thai language and #thailand is for other languages speaking about Thailand. It is a better way to deal with some abuses farang like to post some inappropriate contents in regard with Thai laws. We are only responsible for #thai tag.
I have warned some of them today but I am not so sure, if any of them will take it seriously. Many people don’t know about this rule and some people may not give a damn about it.
Usually, we send them a message very polite saying please for the good of Thai and foreigner community use the #thailand tag, but if they continue we send another message saying that we may flag them. Thank you to warn some of them, do not tell them about the flag because your Rep will not allow you to flag higher Rep but you can tell them some may flag them. Thanks for all :)
