Can user list be kept secure if we contract someone to work on our site?

You should only hire someone that you trust to work on your site, and most reputable coders wouldn't do anything to damage their reputation, which includes things like harvesting user details or spamming your members.

Always check someone out totally before hiring them to do some work on your site, and don't be afraid to tell someone that you don't want them to do the work. If in doubt, don't use them, find someone else.
