Hi, you cannot add any website with Popup/popunder or iFrames. This is to protect community from malicious autoruns/viruses etc. Previously we gave a chance for adf.ly and most of the time, adf.ly loaded popups with Malware or adults only sites. We cannot help anyone promoting garbage in our community. This advertising is only for professional advertisers who keep the internet clean.
Still you can add your promotional links if they are not violating our rules. We want to help everyone but the safety first!
