At last, a well written article on the issue.

The main snippet is:

###
While this makes SHGb02+14a interesting, the chances that it actually represents an intelligent signal from beyond remain extremely slim. Random chance alone would make it probable that at least one of the billions of candidates detected by SETI@home would be observed on three separate occasions, as was the case for this candidate.
[...]
drifts so quickly that it can only be heard for seconds at a time at a given frequency can only be detected by blind luck.

...And that was the lucky signal.
