i found error. on side. happens thought facebook return email if user succeed login. user logging through facebook login button can deny permission , facebook system return junk or generic facebook email. 1 of users registered , wasn't checking placed junk facebook returned in place of email , didn't notice. later when tried register girl mentioning facebook system returned same junk , that's why logged in account of girl. fix placed following condition in javascript:

var emailregex = new regexp("^([a-za-z0-9_.-]+)@([a-z0-9_.-]+)$");    if(!emailregex.test(email) || email.tolowercase().indexof("facebook.com") >= 0) { }
