PayPal's "Donation" button redirects to viglink.com?

[FireWalker]

This is the redirection link that is ONLY visible if you right-click on the Donation button and select 'Copy link address':

http://redirect.viglink.com/?format...i/btn/png/btn_donate_74x21.png" alt="Donate">



This is the original Paypal code behind the Donation button:

https://www.paypal.com/cgi-bin/webs...bn=PP-DonationsBF:btn_donate_SM.gif:NonHosted">


The same occurs in both Safari (iPhone) and Chrome on Windows.

Right-click this link and click "Copy link address":

<a target="_blank"
href="https://www.paypal.com/cgi-bin/webs...bn=PP-DonationsBF:btn_donate_SM.gif:NonHosted"><img src="https://www.paypalobjects.com/webstatic/en_US/i/btn/png/btn_donate_74x21.png" alt="Donate"></a>

That link doesn't recreate the problem. However, if you visit:
http://cityoflakeland.activeboard.com/t62858138/paypal-is-redirecting-donations-to-viglinkcom

You can make the PayPal link turn into viglink.com. What's the "vig" on that?
