No, you're posting on kbin.social. You're never ever doing anything directly on a remote site. You view on k-so, you vote on k-so, you post on k-soc, and you comment on k-soc. Your actions are then, at some later point (which may be microseconds, or it may be hours, depending on traffic levels on both k-soc and the remote website), relayed to the remote website so the two copies of the community can be synchronised.
