Interesting post by Michael Bonacini. http://bit.ly/pmIdKs
I agree with lightgrunty's comments that we should differentiate between catching people for breaking rules to people who deliberately break them. That said, it is hard to tell the difference unless you have lots of experiencing in reading people. I've personally see people attempt to cheat while playing friendly matches(casually mix hand down and picking up set backrow back to hand). There are such people around. A lot of the situations will not happen for DS WC play.
Another thing I discovered about the blogger app, you can only post full links in your post. It's a really simplified interface at the moment and hopefully more features can added soon
