It is indeedy. However as a world we have had a problem with posters insulting another member called Richard by the use of the common nickname 'Dick'. Therefore it was decided between the World 57 Elder and I than all sexual references/nicknames would be blanket banned.
It's like all things within society, if you take something innocent and abuse it, it becomes contaminated and frowned upon. A select few posters have ruined the use of 'dick' for everybody.
That's not my fault... y'all break the rules and I simply create new counter measures to keep things respectable. The rule still stands. Break it and suffer the consequences.
