There are two possibilities

Either this is the most significant action that anyone has taken in human history (and you never heard about it before, by the way), it's extremely dangerous, and it's being done with no accountability whatever; or it's just a lot of crackpots having an impassioned debate about whether it's wise to provoke the malevolent pixies.

I'm talking about Alexander Zaitsev, a Russian scientist, who is trying to actively communicate with extraterrestrials. Prof. Zaitsev controls one of the world's most powerful radio transmitters, a radar system normally used to study the solar system, but he's using it to beam messages to nearby stars. Some people in the ET searching business consider him to be engaged in unauthorized diplomacy. Others are concerned that he may attract undesirable attention.

Personally, I don't think there's much chance that he will stir up any powerful entities more malevolent than the present occupants of 1600 Pennsylvania Ave., so I say go for it. Maybe they'll even bring the long-sought cure for male pattern baldness.
