A screen in your own venue is part of how you present yourself. So the advertiser does not decide alone what runs on it.
What happens automatically. Your own sub-industry is blocked. No bakery ad runs on a bakery's screen. We block the sub-industry, not the whole category — a hotel does not block restaurants just because both are hospitality.
What you have us block on top. Tell us the industries you do not want. Alcohol, gambling, a competitor down the street — we record the block for your screen. Today that runs through us, not through a switch in your dashboard. We would rather say so than claim otherwise.
What is checked first. Every creative is reviewed before it goes out, before it reaches any screen at all. Rejected creatives run nowhere.
What applies to your own content. It goes through the same review. Free does not mean unchecked.
If something still does not fit. Tell us. We take it off your screen.
