Sanders campaign says it has raised $6 million in its first day

19. Funny thing is, for small donations

there is no requirement to collect any sort of identifying info.

Per the FEC:

Contributions of $50 or less
In advisory opinions, the Commission has recommended two possible accounting methods that satisfy recordkeeping requirements for contributions of $50 or less:

Keep the same information required for identifying contributions that exceed $50 (amount, date of receipt and contributor’s name and mailing address); or
In the case of small contributions collected at a fundraiser (such as gate receipts and cash contributions), keep records of the name of the event, the date and the total amount of contributions received on each day of the event.

And--equally interesting--a $27 dollar donation repeated 100 times just so happens to meet the maximum contribution limit from a single source (as of 2018--this limit is raised for 2020).
