Pornography in ecards

[AmerGarRes]

I'm just noticing a weird trend in ecards. I'm seeing cards in which the sender and the recipient are the same. When you look at the card, it's always the SAME image, but the message contains pornography. The e-mail addresses and the IP addresses are always different. The senders are always guests, which is permitted on our site.

Not sure if this is something to worry about. I've been deleting the cards. Has anyone else seen this before?

Thanks.
