I was informed of some of these tools in unsolicited emails to ‘admin’. The sender had to be human and not a robot to have understood site structure. Use at your own risk. The sites have no ‘about’ information. The first thing I ask myself when I encounter any new site or product is “How do they make their money?” since everything has a cost including this site (I don’t make any money as I write this).
