The FaZe Clan won't have to worry about their subathon getting interrupted by the cops again ... 'cause TMZ Sports has learned the house that got swatted this week has been placed on a special location list to prevent similar issues in the future.
As we previously reported, cops and an ambulance rushed to the esports organization's current L.A. HQ after receiving a disturbing 911 call on Thursday ... when a man claiming to be 60 years old stated he killed his mother and brother -- and someone was still breathing inside the residence.
