I don't think having a "banned" editor like me as a moderator would be such a great idea, giving opponents something else to attack the list about.
On the other hand, having someone not overly involved in editing en. Wikipedia or any other project where opponents of gender gap efforts hold sway also is a good idea.
The editor most recently banned here was in tight with those editors who attacked GGTF and brought a bunch of nasty allies to the arbitration, so that's one more thing they have against the list now.
Also, I'm not even sure who the current remaining moderator is besides Kevin. And two to one female better than opposite.
This is what is listed here
