Communications in social networking environment are monitored and patterns of sharing a communication are identified. The patterns of sharing are compared to one or more criteria. A first probability of false information in the communication is determined. Responsive to determining the first probability of false information in the communication exceeding a first threshold, an additional validation of the communication is performed. A second probability that the communication contains false information is determined based on the additional validation. Responsive to determining that the second probability indicative of the communication containing false information exceeds a second threshold, an action to reduce dissemination of the communication may be performed.
