Let's see what happens when I pass the transaction through a transaction analyzer on the Bitcoin blockchain.

After using your service, and trying to find some link using
https://www.kycp.org/ and
https://oxt.me/ I failed to find any meaningful link.
The only thing I found interesting is that the transaction that gave me the coins came from Coinbase several transactions before. Also, after mixing I found a transaction going to Coinbase, or that was my impression.
In general, the service was quite fast, some bugs regarding the loading of the page, maybe the server can be prone to DDoS attacks in the top layer of the internet, using TOR may solve the problem.
