Background Pony #945D
The tag 'Predator Drone' implies 'plane ponies', which has been aliased into 'plane pony.' However, plane ponies does not convert into plane pony if set by implication, rather than manual tagging. Due to this, the implications of plane pony are not set.
Furthermore, the image will not appear in searches for plane pony, and as plane ponies is an alias of plane pony, it cannot be searched for using the old tag. If the tag counter is accurate, there are more images tagged this way,
but finding and correcting them is tricky due to the search issue. Additionally, plane ponies cannot be removed and replaced with the correct tag.
