It Reduces the visibility of your content: There is a possibility, that banned hashtags in your content will cause the hiding of your post from public feeds and searches. Hence, it can severely limit your audience. When the desired audience can not see the content, it is difficult to build engagement in the community.
Risk of account shadowbanning: Like Instagram, they may shadowban one's account if any form of the banned hashtag is detected in content. What shadowbanning does is make your posts invisible in searches regardless of the content quality.
They Leave a Negative Impact on Credibility: The banned hashtags in your content reflect your spam-like behavior or bad judgment of the audience and the platforms. This can spoil your image and discourage followers from trusting your content anymore, leading to fewer likes, fewer comments, fewer shares, and eventually, poor engagement. That means it struggles to provide the most likely traffic and shun the power of your social media efforts.
Increases the risk of potential account penalties: Banned hashtags often lead to grave warnings, temporary restrictions, or even permanent bans of your account from the platform. Always protect your accounts with penalties as a priority matter.
Your account could be considered violating community guidelines: Banned hashtags break the community standard, and when you avoid them in your content, your posts are by community rules and help in forming a healthy digital environment, resulting in the good health of your account and credibility as well as this practice improve the overall quality and reach of your content and your social media presence.
