Unless you share your actual preset's files from it's folder in your "My Presets" folder or it's fhp file from your "Presets" folder to others no one else in game can see you in your preset.
If you want others to see you in your preset but not be able to use it themselves you can export it in your preset maker and then go to your "Presets" folder. There you should find a file that looks like this:
yourusername_
thepresetsnumber.fhp
Just upload that file to any file sharing site like mediafire.com etc and then share it's download link with whoever you wish
