Yes, judging by recent articles, the law works. Commenters above are right to some extent.
However, I'll tell you my way of "deleting" :). Happened six years ago.
As is known, the Contact does not delete the account after three months of inactivity (although it should according to its own rules, as I recall). However, after 2 attempts, I decided to follow the advice of one of the commentators here, on habré. The most difficult was to find a form or a contact that allows contact with real support. Many users, therefore, configured a bunch of obstacles in the form of a FAQ, answers many questions on subjects and without... In the end I found what I needed.
I described the situation of compliance with the terms, and then politely sent the administration and the entire service to the devil in the form of a set of mats...
In an hour I could not log (there was a message that the email was in the "black list"). Friends have reported that from the search I also disappeared (although the events could not be linked).
The goal was simply to remove uchetku. I think that happened fairly quickly :)
