“Some of the Instagram Services are supported by advertising revenue and may display advertisements and promotions, and you hereby agree that Instagram may place such advertising and promotions on the Instagram Services or on, about, or in conjunction with your Content. The manner, mode and extent of such advertising and promotions are subject to change without specific notice to you.”
And these are the updated ones (which will enter into effect in January 2013):
“Some or all of the Service may be supported by advertising revenue. To help us deliver interesting paid or sponsored content or promotions, you agree that a business or other entity may pay us to display your username, likeness, photos (along with any associated metadata), and/or actions you take, in connection with paid or sponsored content or promotions, without any compensation to you. If you are under the age of eighteen (18), or under any other applicable age of majority, you represent that at least one of your parents or legal guardians has also agreed to this provision (and the use of your name, likeness, username, and/or photos (along with any associated metadata)) on your behalf.” (highlight mine)
Holy right creep, Batman!
