[Russell Sobie]

The easiest way has been discussed in the thread already: make your preview.jpg something that is obviously not the default preview.jpg you find on stock skins. If you are really paranoid about it, don't even include a picture of your car in the preview.jpg. Not likely that people will pick your skin then if they can't see how cool (or ugly) it looks at livery selection.

At livery selection the website is looking at the available skins you have saved for any given car for a race you are signing up for, but it can't tell the difference between a custom SRS skin (firstname_lastname) from any other skin you have on your hard drive (including stock skins). With the number of cars in AC, I don't think that would be a worthwhile addition of functionality. You'd have to like... create a database of all of the stock skin names for all the cars you'd ever have a racing series for, and compare against that? Or change the functionality of the SRS skin app to not only upload skins, but also report in to some central database saying "skins named russell_sobie are SRS skins" and then the livery page checking in with that data base to see if someone is trying to select a registered SRS skin that doesn't match their name.

Seems like a nightmare to set up, and as annoyed as some folks in this thread seem to be at other people using their skins, it really isn't that big a deal in the grand scheme of things. I've been in races where someone using my skin (that was not me) was the most annoying guy on the track that day.  At this point I just shrug and keep racing. I still offer them my free livery service, but again, still no takers.
