This seems very questionable for many reasons:
1) The only way to donate is through her GoFundMe account.
2) There is the "There are numerous expenses involved with setting up an event to break a world record. By far, the majority of these costs are due to the stringent documentation requirements of Guinness. We are seeking your help to offset this and maximize the money raised for The Herren Project. " statement. Basically there is no commitment to donate a minimum percentage to charity.
3) There are lots of marketing items for donors, T-shirts, wristbands, photo with Tara etc. Is the purpose of these items to promote the charity or promote her?
4) There are requests for corporate sponsors. Again the same comment applies, promote the charity or promote her?
5) The link to the charity, The Herren Project, does not take you to The Herren Project home page, but rather a page within Tara's website. If you want to donate directly to The Herren Project you have to find the page yourself.
However, she is actively campaigning for witnesses so I suspect she is seriously attempting to achieve the record.
