btw it is possible to request the removal of a hit as well.
You got zero chance. Reuters gathers the information from multiple sources such as US sanctions lists and from global sanction lists from around the world. It even scrapes from reports on the internet. Most banks just do a search of name and if it matches along with data of birth that call it a "worldcheck hit" and they don't really care about the reason your in their they just won't touch you.
Sometimes the information it contains is wrong but Reuters do not care as its the users call as to what action to take. Banks and EMI's cannot also discuss with the client or pass on to the client what information they found. I guess this is Reuters way of making sure they don't get sued by customers for incorrectly putting information about them that is incorrect. The database is quiet extensive and contains not just people that did things wrong but PEP's (Politically Exposed Persons) and their entire families i.e cousins, uncles, aunties etc. How they gathered such private information I have no idea .
I was sometimes wondering why someone doesn't setup a "remove yourself from all of the world's KYC/AML blacklists" service lol...
Secrecy and terms and conditions given to users of the blacklist data makes this impossible. You will never know if your on the blacklist in the first place, in order to ask to be removed, unless its a public list or unless the bank tell you directly that you are on a list which they won't do.
