Yes. The codes are safe and doesn't harm your visitors.
Sometimes, people might think that using PTP will risk your visitors.. That's bullshit! it is 100% safe. I promise! I've been using PTP for a long time and I can guarantee that these three networks (Paid-to-promote, Ptp123, and Advpoints) are safe.
Tip : Place the codes in the bottom of the page, before the </body> tag. That way you'd still earn money, but the loading of the PTP code won't interrupt the loading of the page itself.
