While I would be the first to say those squares are meaningless without context, if someone led others to believe they were the result of anything other than automatically generated posted and didn’t have a legitimate reason like the one I posted, that might potentially be fraud, especially if it was used as a basis for future economic exchanges, such as employment.
Using GitHub green squares as a basis for offering employment is as stupid as using the color of their hair. Don't play stupid games if you don't want stupid prizes.
