The general consensus for using promotion services now is to decline rewards. Bot services are not quality oriented at all, they upvote what they are paid to upvote. 

There are better ways, such as the new Curangel project, and the HoboDAO project that we're building is a decentralized contest curation system that allows a group of human curators to decide the top 5 daily posts submitted to the HoboDAO for review and curation rewards. 

Contests and human curation services are ultimately a lot better of a system. However, if the bot services wish to continue, the community is recognizing that it is acceptable if rewards are declined. Ideally, #NewSteem should just embrace new human curation programs and give up on the idea of bot services, which is a point many outside commentators have criticized Steem for having.
