Shadowban
Shadow Ban
A covert restriction where a platform limits the visibility of a user's content without notifying them, reducing reach and engagement.
Chi tiết kỹ thuật
Social media shadowban requirements change frequently as platforms update their layouts. Current standards: Facebook cover (1640x856), Twitter header (1500x500), LinkedIn banner (1584x396), Instagram square (1080x1080), Instagram story (1080x1920). Profile images are typically displayed in circles, so important content must stay within the center safe zone. Most platforms compress uploaded images to JPEG at 75-85% quality, so uploading PNG originals preserves maximum quality through one compression.
