@beforewisdom here on kbin all mastodon posts are pulled in for us to see. we do content organization a bit different (putting things into threads, for example). This post you just made was automatically sorted into our @fediverse magazine and is listed as a "microblog post". The only way to prevent this would be to defederate with kbin (blocking kbin). Otherwise we can see your posts like everyone else on the fediverse can.
