Glad you didn't give any contact details. As we note in the post, it's advisable to run a virus scan, especially if you interacted with the site in any way.
For future reference, we'll never intentionally forward people to a site other than the one they are trying to access, and when using outside services (for example, when we run real surveys of our own) we'll always include reference to the AO3/OTW, a link back to our main homes, and where possible use our logos. So, if you see something unexpected when trying to access any one of our sites, it's a good idea to assume something has gone wrong and to leave that site and let us know what happened.
It's amazing how much impact one little typo can have!
