Random payments with Blockchain wallet ID's

[Eotnak]

I have an account I only set it up because I was able to set my username I don't use it for anything, but I have gotten a couple payments for $25 with a Blockchain wallet ID in the comments.  I though it was someone trying to mix them up, but I couldn't figure out how to send BTC to the wallet ID without a Bitcoin address.

Any ideas?  Otherwise I'm just going to keep them and enjoy watching my wallet grow.

You basically received a payment from someone and you want to return the money back ? If you know your receiving address then just type it on blockchain.info or any other blockexplorers and you should be able to see the transactions and that includes the sender addresses.

I figured I would take a percentage, but sending back to the sender's address would not mix them, If I'm not mistaken.
