There are some negative consequences to being anonymous on the Internet. Deindividuation, where self-awareness is blocked by environmental conditions, can occur and be problematic. Some consequences of deindividuation include the reduced ability to control one's behavior and engage in rational, long-term planning, and the tendency to react immediately and emotionally. A person who is lacking this self-awareness is also less likely to care about other's opinions of their behavior. This all can lead to increased hostility towards others and the formation of anonymous hate groups.
