[Inkscape-docs] prevent email address as username on website?

Hi Friends, I was just looking at the gallery today, and noticed a new image that's been uploaded. And I happened to notice that the user name is an email address. Is there any way to prevent that? It seems like this has been briefly discussed before, but I don't remember which solution was proposed, if any. Or is it not considered to be a problem? To me, the use of email addresses for username is just another way for spammers to harvest addresses. So it just seems prudent not to contribute to that problem. (Or if nothing else, not to have a lot of spammer traffic).

Thanks, brynn
