Indiegogo wants every campaign to be successful. Remaining in touch with your backers plays a vital role in ensuring positive and open communication, and allows you to foster a vibrant community. Backers want to stay up to date throughout the entire lifespan of your campaign and be kept in the loop about your campaign's progress.
The Comments tab on the campaign page is a place where backers can provide feedback and discuss all of their questions and concerns about a campaign, both with the campaigner as well as with other backers. It's also a great tool for sharing information, and is an expedient way for you to address individual backers' queries. Maintaining a productive dialogue with backers via comments keeps the process transparent and can be a good tool in addition to your own customer support channels.
If a backer is posting repetitive comments, advertisements, or comments that are not relevant to your campaign, you can mark the comment as spam by selecting the blue "Mark as Spam" hyperlink below the spam comment in the Comments Dashboard. As a note, comments that are from backers who are asking questions about a campaign or posting feedback should not be marked as spam.
