Amazing - People tweet pictures of their credit cards (twitter.com)

Is basics of social media conduct a class that should be taught in school?

I mean, it's easy to say these are just idiots. But maybe they really don't understand the ramifications...

Since this is already an automated account that finds all these tweets, instead of just retweeting for publicity/humor's sake, they should add a sentence telling each of the victims why this is bad. At least make sure they themselves don't make that mistake again.
