Hey there, Just to let you know of an Instagram bot that has been working for quite a while now : Automagram. It has free features including one called the Executer where you can create recipes based on hashtags and decide to auto-follow and/or auto-like pictures/users matching these hashtags on Instagram. Perfect to develop niche based audience on Instagram. Still can't post URL due to low post count but don't hesitate to Google for Automagram, easy to find. Reviews are welcome, development still in progress.
