All data in this bug tracker is considered to be in the public domain. Thus we are in general not able to remove your comments because they provide important context for a problem or feature requests. Other reports may link to that comment so that removing that comment would obviously remove data which is important for the development and security of the software.

What we can do is to disable your account and on request remove a clear name from it.. This preserves all your contributions, but will prevent anybody (including you) from logging in under that account. If you change your mind, the account can be re-enabled.
