Really? Wow. Is there any danger from them sending coins to an account?
Thanks for the info!

Edit: What do they gain since a person cannot really tell where it came from? Is it just to verify an account is active at that address?
Very interesting.

It is to attempt to scam people. If you check at blockchain.info, which is the block explorer most people use I think, your allowed to add a message for the transaction in the blockchain.info web wallet. If you look at the transaction, the message on top is advertising a ponzi scam, that probably doesn't even pay out.

There isn't any danger, other than making a transaction larger if the small 5 cents is included as an input.

Thanks for the information. I didn't even see or notice a message.
