We provide... Leverage
What 
suricattus and
matociquala say here, cosigned:
If I am a guest at a convention you are attending, or simply a fellow attendee, and you feel that you have been harassed, intimidated, or that your boundaries have been trampled or ignored, please feel free to ask me for support, help, intervention, or just an escort to a safer area or backup on the way to talk to convention or hotel security.
If you do not feel that you can stick up for yourself, I will help. I will be a buffer or a bulwark if necessary or requested.
Just walk up to me and ask for Leverage, and I promise that I will take you seriously and I'll try to make things better.
