The votes you see are from our Steemvoter 1 freemium service. These votes don't have any order imposed on them but we don't actively randomize them either, which is something we can look at, even though we planned to discontinue development of sv1 to focus on sv2 which has timed and randomized vote capabilities.
As history has shown our posts are not immune to downvotes, but rather the services we provide and post about are liked by many users, so most accept that we deserve rewards for it. Should our post rewards get downvoted, that would mean that BuildTeam would have to charge more premium fees instead of a freemium model. We like to offer both options to give our users the choice, but we will also adapt in a situation where that is no longer possible.
Regarding the curation rewards, the best way to earn curation rewards is to frontrun our freemium guild. That way you are automatically on the front of the queue and our software will detect that and not issue a second vote. This way we reward users who are passionate about supporting us.
