Dear Selva, Monster, Naukri, Shine, etc., I really do not know how many more subscribed portals there are. To the best of my knowledge, one cannot access profiles until a license is obtained. If you have been told, suggested, or guided to use any such tools, it may be illegal. If caught, you could be labeled a "hacker," potentially leading to serious criminal charges. Once under scrutiny, you could be in serious trouble.
Alternatively, you can develop contacts locally to enhance your database. This means you can utilize LinkedIn, perhaps Facebook (I am not sure about Twitter). Simply post a job vacancy and request interested individuals to send their profiles to your email ID. It would be more credible if you use your company email ID. Otherwise, potential candidates considering a change may perceive it as a trap set by HR. I hope you understand my point.
Please let me know if you need anything else.
Best regards, [Your Name]
