The survey is how Autodomme learns what you want and where your hard limits are — it drives your kink ranking and every task you're given.
The BDSM survey is where you tell Autodomme what you actually want — and, just as importantly, what is off the table. Without it, everything you are assigned is a generic guess.
The more you tell it, the better it fits. Revisit your survey any time — your interests are allowed to change.
