Let me know if this is a possibilty that can even be done:
Can a 'robot' be built that would do the following:
-Find trending articles/pictures based on a set of keywords and put them in a 'content bank' to be weeded through and scheduled for posting on hootsuite. The content bank wouldn't post to any social media account it would just be a catch all for the manager to get content from.
-Unfollow inactive or spam accounts specifically for twitter.
If you developed this already let me know. Let me know the time it'll take to make this bot and the cost.
