Instagram activities outside the social network, perhaps?

Question

Instagram

Is it possible to implement the following scenarios with the Instagram API?

1) The user presses the subscribe button on the site and the subscription occurs without going to the social network.
2) The user presses the like and the like is placed under the entry where necessary.

Is it possible to carry out the above mentioned actions without special actions aimed at subscribing or liking them. For example, only by going to the site or clicking on the link, provided that the user is authorized in the browser on Instagram. Since I often found that I was subscribed to profiles that I definitely did not subscribe to and, I think, many met with this.
