Fandom Trumps Hate

Would you consider having it be opt-in for future auctions, maybe? It seems like it'd be useful for potential bidders to have a platform-agnostic way of getting in touch with creators privately for, say, clarification on if they'd be willing to handle certain subject matter that's not covered in their interested in/do not want lists. Obviously not everyone's comfortable with sharing their email address publicly though, so having a (required) question on the sign-up sheet to specify whether or not that's cool might work?
