it is a good idea to check the IP of all employers who sign up.
My site is in Canada. so anyone from Africa Euro etc, I see no reason why they need to post jobs and I find that 99% of those posts are scams, MLM and junk.
I recommend always seeing if the employer is in your country before you approve them. Folks in India post a lot of jobs, but 99% are real as they work for outsourced companies.
use the link above to check where the IP is coming from.
