I find this quite exciting, not because I hope for a signal from an intelligent civilization, but because it might point to some new phenomenon.

When pulsars were discovered, they dubbed them LGM-1, LGM-2 etc for "little green men", (see https://en.wikipedia.org/wiki/PSR_B1919%2B21 ). The radio signals turned out to have a perfectly "normal" source, with exciting new properties.

There's always the off chance this time, it's actually caused by "LGM", but for now we should think of these signals as an observation that needs an explanation, not as caused by an alien civilization.
