I realize that Geek Gold is an imaginary currency invented for our use here on BGG.
And I appreciate the ability to review my GG transactions (both incoming and outgoing), too.
What potentially bothers me is that, as a site supporter, part of my real-world personal financial information is available to these same people - anyone browsing my GG transactions can see how much I have contributed to the site by spending the time to look through my transactions and seeing how much BGG has added to my account.

Right now, the page is cluttered with income from the game lotteries. But if you go back a page or two, it becomes clearer.
There are a few transfers from BoardgameGeek to me. BGG transfers GG for corrections and for financial contributions. Corrections pay out ... not very much. .25 GG. Financial contributions are $1 per GG, so Transfers from BGG to me that are $1 or more are financial contributions to the 'Geek.
If you wanted do, you could do the homework and figure out my monthly contribution and when it hits.
Not a big deal for me - I'm not a big donor - but this transparency may keep some privacy-crazed folks from donating, and there are other users who may donate a lot that don't necessarily want that information available.
