Almost all the best carriers label spam callers to prevent spamming. Most carriers label spam callers by words such as “Spam Likely” or “Fraud Risk” or “Marked as Spam by many others.”
In such cases, users only need to understand such labels as warnings. For example, T-Mobile, one of the largest US telecommunications companies, makes use of the term “Scam Likely.” Sometimes the company uses the Caller ID screen to label spam calls as “Nuisance Likely.”
All of such terms mean that according to the telephone carrier’s systems, the call is highly likely to be a robocall or spam.
