Don't! Buy! Thai! was a campaign initiated in the early 1990s by child welfare advocate and author Andrew Vachss to boycott goods and services produced in Thailand until its government introduced formal and practical reforms to significantly curtail the prostitution of children. The organization of Don't! Buy! Thai! was willfully informal, with promoters refusing donations. In 2000, frustrated by the lack of traction and noting that the prostitution of children to sex tourists had become less concentrated in Thailand, Vachss and most of those involved abandoned the boycott.
