Skip metrics created by Machine user in the community

Hi,

We are using a machine user which creates posts (TKB) in some hidden boards by fetching post content from third party.

But this machine user (since it is creating many posts) is significantly effecting the Lithium Social Intelligence analytics, metrics for superusers, casual users, observers. and CHI scores about the community..  

We have read the article about “Skip post metrics”, will this solution solves our problem? If yes, is there any way we can apply this solution for specific boards?

Please guide us the right approach to solve the issue.

Thanks & Regards,

Phani
