At WaybakMachineDownloader.com, we donate 10% of our profits to archive.org, in order to support them maintaining their servers and web development.
However, in case you want to make direct donation to the Wayback Machine, you can do so yourself here: https://archive.org/donate/
The Internet Archive is a non-profit organization that relies on gifts, volunteers or paid staff that could otherwise get a much higher salary at a commercial organization. Besides that, they operate their own data centers in San Fransisco, Amsterdam and Alexandria (Egypt).
If you provide us with a evidence of a direct donation to the Internet Archive of $25 or higher, we grant you a free whole website recovery. Please send us a screenshot of both the "Thank You" page on archive.org, and a screenshot of your credit card or paypal statement. Send this to email@example.com and we will manually initiate the scraping within 1 business day.
