What is an anonymous contribution?
You can anonymously contribute to a campaign by choosing this option during the contribution process. Your user will be created in PPL for management purposes (to receive campaign updates or your contribution back in case the campaign fails to raise the needed amount) but your personal information (name, e-mail address, picture, etc.) will not be shared with the promoter of the campaign nor the general public. The contribution will be listed as "Anonymous" in the "Investors" tab.
Please note that by doing so you will not be entitled to receive any reward.
