Reporting them is absolutely the correct course of action, right-click report.
As to your name - no it’s not appropriate. Not ingame, not here.
Looking at this license, I sense a theme, and not only has this one been marked for a namechange, 7 others were found as well. Not something we normally do, but given any of these would rack up penalties if reported you have a chance to avoid that.
When you next log in to those characters you will be given an opportunity to choose a name that conforms to our naming policy.
When folks here give you advice, or a warning - it’s usually a very good idea to heed them.
