The act of eliminating visible identifying marks added by the Instagram platform, often related to content sharing or branding, is a practice undertaken for various purposes. An instance of this would be the removal of the Instagram logo and username that is automatically overlaid when content is re-shared from Stories.
This process is undertaken to provide a cleaner aesthetic, repurpose content for different platforms without attribution to the original source, or maintain a consistent brand identity. Historically, users often sought ways to accomplish this to have more control over the visual presentation of their content. This offered flexibility in marketing and content creation.
