American company ‘American Apparell’ posted a picture of the 1986 challenger explosion on their tumblr account on the 4th of July with the hashtags #clouds #smoke. The picture was posted by one of their PR team who was born after the accident and had no recollection of it. The team felt major backlash and shortly removed the post.
Mistakes like this can be easily avoided by properly sourcing and research photos before posting them on a social forum for all to see.
Prior preparation prevents poor performance.
