I own a website ( Ostetso ) that is targeted at iOS app developers. We provide cloud services for developers who want to add a social network into their apps. On the website, users can download our SDK and register for our service. Over the past week or so I have noticed about three or four registrations a day coming in from users with email addresses at the same 163.com domain. The email addresses look as if they are bot generated and these registrations all seem to me to be fake accounts.
I can't think of any reason why someone would want or need to create fake accounts with us. Does anyone here have opinions on that? Is this something I should be concerned about?
