You are right that Steemit is a decentralized social media platform that provides users with revenue in the form of SBD votes. Generally, Steem curators and currently Popular voting services vote on quality content from users. Interaction between users through upvoting and commenting on posts Is also an important part of this platform. Quality posts usually get an upvote from the Steemit team.

Bid-bots generally don't care about the quality of the content they choose. They vote on user posts based on the financial compensation received. This can indeed be considered unfair To users who produce high-quality content but don't get the attention of upvote bots. This situation may affect the quality of content curation on the platform as a whole.

Good luck.
