Inclusion on a list is an administrative designation, not a criminal conviction. Designations can be challenged and are periodically reviewed; entries marked “no longer listed” have been removed from the respective list. The legal effect of a listing depends on the jurisdiction and the programme concerned.

Compiled automatically from official public sources. Name similarity is not identity; nothing here is a legal determination or allegation of wrongdoing. Verify against the linked official source before relying on any information.
