Hello,
In 1998 and 2001, there were violent conflicts in Kalimantan between local Dayak tribes and Madurese who had been settled trough the Indonesian government's transmigration programme.

Many people were decapitated and heads were missing, so it appears that some Dayaks can still resurect the old practice if pushed too far.
