I have been told that to ascertain if your data is included, you have to supply more data to specifically identify you. Not unreasonable in the first instance, but why so much info to say - yes you have been compromised...Surely a name 'Fred Bloggs' is or is not included. If it IS included, then is is up to you to pursue if indeed it was your Fred Bloggs data. If Fred Bloggs' name is not on the list, you can remain anonymous.
How hard is that?.
