Make it very clear that you're aware that anybody, regardless of their race, their gender, their sexual orientation, their socioeconomic class, or really anything else about them, can end up in an abusive relationship or situation, and that you're there to help.
Seriously, if you're doing a Spring Clean of creeps and you even IMPLY that you're aware that men get abused too, men will come forward with their own stories about the creeps you're already investigating. This happened on my community.
