How closely does Airbnb watch messages with guests?

[Daniel Murphy]

For context, we built a local area guide (under construction) for our STR area. This also includes our direct booking page and every page of the website, has a link to our direct booking page. With time, we hope to build more articles & get this to rank in google which should bring more direct bookings.

1) If a guest asked for recommendations (through the Airbnb app) for local attractions, restaurants etc.   Currently, we have not sent the link to our website because it contains a direct booking link. 

2) We also send out a handful of links to private youtube videos we put together for various FAQ's (how to use door lock, pool cover, unlock interior doors etc.)  I'd like to add an outro to these videos with a link to our local area guide / direct booking site 

My question is, how closely does Airbnb monitor these links through their messaging app? IE - we don't want to get red flagged or kicked off of the platform because we are promoting our own direct bookings.  However, if it's a link at the END of a youtube FAQ video, will Airbnb ever see it?  
What are your thoughts on all of this? I want to tread carefully & stay below the radar...
