The specifics of this - the request to judge a prize one is clearly unqualified for - are we as software engineers particularly vulnerable to? Most people would, I think, conclude "this is fake, because why would I be asked to do this?". But I often think that as software engineers we fancy ourselves to have more insight into other fields than we really do. Does this ring true to anyone else?
Falling for this phish woudln't need to be a matter of inflating one's opinion of oneself, it could simply happen by knowing that at the low end of contests, the bar for judging is low.
