I am so annoyed to find out that SweetCaptcha has been forcing my site visitors by hidden codes to pop-ups ads through (clktag.com/ clkctk.com and http://www.revenuehits.com/) without my permissions u better scan ur site using google chrome java script console .. So bad !
To simulate the error use this:
Technology has changed now we have [tippy title="mailing list"]<b>a list of the names and addresses of people to whom material such as advertising matter, information, or a magazine may be mailed, especially regularly.</b>[/tippy] management services that will guarantee to deliver to the Inbox such as <a href="http://mailchimp.com" target="blank"><span style="color: orange;">Mailchimp</span></a> and <a href="https://www.aweber.com" target="blank"><span style="color: orange;">Aweber</span></a>.
Sorry yes it was meant to be this 🙂
