Because consent is THE biggest part of responsible BDSM, I feel it should be possible for custom characters uploaded to RackNet to "Opt Out" of certain fetishes / sexes / genders if they so choose.
EG: You want to upload your Character to RackNET, but you're grossed out by Watersports, and don't want your character to be used for such activities. You would be able to mark Watersports as a "Hard Limit", which would disable all Watersport activites from being enacted on your Character.
OR, say, your character is a strict Lesbian - mark Male/Man as a "Hard Limit", and no one with a Male/Man Scientist will be allowed to use your character AT ALL during a session.
TL;DR - Create strict protections for custom characters, should their owner want to enable them.
