New Registrations to my gallery?

[gmbunk]

I am now receiving numerous registrations to my gallery with usernames that are all similar in format, i.e. "htpi343", "ulpq077", "fpoe442".

Does anyone else see this?  My gallery has a unique url that really only friends and family would know about.  How am I getting these random registrants and where do they come from?

Anyone?

Your gallery is probably in google. Use the captcha plugin to deter them.
