With Monitors Enterprise & Professional, we're able to do this with ease.
To get started let's head over to your Create/Edit monitor view.
In your Monitor, let's create your first rule:
Include Posts With + Any + Words: #hashtag
Next, let's limit this to a specific profile or profiles. Note: Handles do not require the @ symbol infront of the username.
AND + Include Posts With + Any + Social Profiles + (Twitter): @profile
Voilà! You've created your first hybrid monitor.
Now, whenever @adidas mentions #crazy, it will be tracked and pulled into the Monitor.
