Not to alarm anyone, but it would be useful in the long run to have some kind of authentication on a site like that. Virus scans are one thing, but those don't protect from malicious pranks or people abusing the site in other ways. If you don't want to add your own site registration, OpenID might be a useful alternative. This would allow people to log in with their identities from Google, LiveJournal and many other sites.

I could still register as lesbentley on some site that offers OpenID and use that to upload a package that promises to shape Antonia's breast in new and enticing ways, while in reality just opening a window that says "Gotcha, perv!". But then the real lesbentley would eventually spot that and could inform us that the person uploading as lesbentley.dubious-host.org is not him.

As I said, I don't think there's anything to panic about just yet, but this might be something to keep in mind and consider for when the site becomes popular.

(Apologies for using your name, Les!)
