I don't know if I'm going a little bit mad here, or if this is actually an Ethereum address collision. I have installed Parity onto a brand new computer that I had custom built. The machine had not been turned on before today.
During Parity set up I created an account like normal. But the first thing that I noticed was that the balance of the account was none zero.

I'm gathering more info. But this is weird.
Ok update, I definitely have control over this account. I've made this transaction: https://etherscan.io/tx/0x33a1b81eae1c1d5f542c69960e3ace67177d61dd633639d41972ec603c73a96b . In it you can see that I sent 0.0016347 Ether which is the same number as appears in this URL Did I generate an existing Ethereum address in Parity?, the URL for this question.
I don't know how to prove that I have never controlled this account before, but I have never controlled this account before. This is definitely an address collision.
I'm not sure what this means, did I hit a one in a bazillion chance just randomly? I'd really like for some feedback about what I can do to prove my case. What are the implications for the Ethereum network?
Update
Ok I've had a look over what happened. I think this issue maybe related to an empty seed phrase account.
When I got to the create account stage, the computer froze for over 30 minutes, I restarted the parity client. Once the application loaded up again I was prompted to create a new account, I did and this time was able to create a new account, but no option for a seed phrase.
The next thing I noticed was that Parity gave me notifications of Ether deposits, I thought, "hmm! Parity must be giving you some faucet money now", but then I saw that the account had lots of transaction history.
This looks a lot like user error / Parity bug.
From the look of it, it seems like others are able to access this account from the more recent transaction history.
