I have meticulously read through similar questions, answers and their comments but I still do not understand how the deletion is done. From what I understand I email the customer service and then they do what exactly?
1) They disable my account so that I can no longer use it?
2) They reassign all of my questions and answers to some other account? To which one?
3) They delete all my questions and answers so that they go away from public view?
What is the flexibility (if it exists) of the deletion procedure? Is it possible to erase the traces of my former association with the site. Can I request any of the following be done?
4) All of my questions and answers be deleted from public view?
5) Some of my questions and answers be deleted? If yes what criteria?
6) Can I have all of my contributions be assigned to some other account which runs as sort of a "collective account" and already has tons of content so that it doesn't happen like my contributions just move to some other url but still stay grouped under that location and therefore that location can be discovered as representing my account?
7) Can I have my contributions dispersed through several "collective accounts?
8) Can my current public name be removed from any comments to my posts so that my posts cannot be identified later as once belonging to me?
Please be polite with me. I wouldn't have asked if I have found the answer in the other questions. The other questions are also old and it is not clear what the situation is as per 05/2012.
UPDATE (for those interested):
I asked the Stackoverflow team about the procedure. Apparently none of the points 2-8 I asked above are possible, only 1 will take place. The link to my user page from my contributions is going to be removed and replaced with non-clickable text of an anonymized user name like "user1234". Whether this number is the same as my current user_id is not clear. That's all the information I got.
I'm going now to rename myself to "Anonymous" then request the account deletion. Those interested in the procedure will witness the exact result on this page.
