OK, so how do you know you've got the right sender? Like others are saying, if you can only trace the sender correctly in 1 of 15 transactions, you're not beating randomly guessing. You'll guess correctly 1 out of 15 tries, and you'll have no way to verify you were right. What's your methodology for verifying correctness on that 1 of 15? If you have that then you might have something, because if not then you've got no way to know which out of 15 was the correct guess.

Dude that isn't tracing... You could already do that with any Monero block explorer. Click any tx hash in a block and you can see a pubkey. See this is what I mean about you using terms in unorthodox ways. By the way is that your transaction? I see it was made yesterday
