To use internet services anonymously is a right guaranteed by law (at least in Germany and Switzerland). Privacy is not a crime also from my personal point of view. (Of course you are not really anonym easily. To reach that goal it needs a bit effort.)
Therefore it is possible to use this forum using a pseudonym. See:

Experience has shown anonymity is been abused very often. Therefore the accounts of pseudonym users may be deleted faster if there are indices that the account is used for trolling for example. Users using their real name get a leap of faith in the beginning.
It is possible to make trouble using your real name or to be a respected member of the forum using a pseudonym. If you think about it you will find examples for both cases.
The account of this particular user has been deleted for reasons I don't discuss in public. After that the forum software has replaced the name by "Anonymous" and changed the status of the member to "Guest".
