LOL. I'm not going to deanonymize datasets for an internet stranger. Certainly not for free, but also not at any hourly rate unless I know that the organization employing me either has the original non-anonymized dataset or at least have very strict internal controls about how deanonymized data will be handled.
(I also haven't done this work in a LONG time, and there's now a whole lot of academic work on the topic that didn't exist back then, so there are probably much better consultants for legitimate organizations looking to hire for this work.)
If you want proof, you can use google to find LOTS of papers along these lines analyzing real datasets. I think https://arxiv.org/pdf/cs/0610105.pdf is a fairly typical example.
