Hundreds of researchers spend their annual work time looking for alien life signs. They find occasional radio signals, but they often turn out to be easy to explain. In order to avoid creating extraterrestrial alarms, researchers propose a classification system called Rio 2.0, which will attempt to establish the probability of veracity for each reported event.

Signals that will be categorized using Rio 2.0 ratings will then be verified by other researchers and noted again the system is not exactly different from a scale for earthquakes such as Richter or Mercalli. Rio 2.0 can be used in large part by anyone without much training in the field. Most of the phenomena recorded in Seti (search for extraterrestrial intelligence) can easily be explained, often by antennas by taking signals from circumstantial transmitting stations, or recording signals due to poor calibration or other malfunctions
Of the events recently recorded using methods to search for life outside the solar system, one can mention the megastructure around a star, which was thought to be built by an advanced civilization, which turned out to be false and the "wow" message which Russian researchers recorded as believing it was from space. Using the Rio 2.0. system, these findings could be categorized and then checked by other researchers to arrive at a conclusion before this type of information reaches the press, which could risk further falsifying.
