Speaking of scams (somewhat related, but slightly off-topic):
There was an individual who recieved a Nigerian Spam e-mail who, instead of just ignoring, decided to engage the spammer by creating a fake persona and e-mailing back and forth over a number of months.
The whole exchange, although long, was rather entertaining, and he's written it up as a one-man comedy show that he takes around with him.
I thought it was very interesting how the comedian in question chose to engage the spammer, and potentially stop him from spamming in the future. At the very least, probably took up a lot of the spammer's time and attention that could have been directed at more gullible marks.
Here is the link if anyone wishes to check it out.
