For some users, Facebook’s photo tagging is a new fun for them when they want to share their photos with their friends, and showed that the one who tagged also a friend in their inner circles. However, this has brought the issue of photo-tagging spam.

According to AdvertisingAge, the so-called photo-tagging feature has been used as a tool by guerilla marketers to make the photo appealing to the Facebook users. For example, if your friend has been tagged by someone, and it’s appealing enough for you to click the photo as appeared in the News Feed. After you clicking on the photos, it’s in fact relevant to some marketing promotions in support for a particular candidate or event.

Sam Lessin, the founder and CEO of Drop.io reported that photo uploading and sharing is central to Facebook’s overall service offerings. He said, “In Facebook, photos have several characteristics that make them especially fabulous marketing vehicles. First, people love them and tend to click on them all the time. Second, they get incredible real estate in news feed. Third, any message put into photos has a strange automatic relevance because it is attached to the name of a friend. Finally, there is a huge curiosity factor as to why a friend is tagged in an image.”

Now, before we, the Facebook users using the photo-tagging feature in order to outline additional details in a given photo, let us think that the guerilla marketers also will use this tactic to provide a link to a marketing promotion or a cause whenever your friends saw it in the News Feed of Facebook. This could be the biggest concern for this photo-tagging capabilities on Facebook at this moment.
