Bitcoin money-bags to the rescue The Tor Project @torproject 16h A big thank you to @HillebrandMax for writing about how the Tor network is critical privacy infrastructure that can only thrive with community support. As a small nonprofit, recurring donations are key for long-term sustainability. bitcoinmagazine.com Tor Is Under Attack And Bitcoiners Must Help Fix It With a lack of funding, the Tor project is struggling to defend against denial-of-service attacks, putting Bitcoin projects at risk. <<< Speaking of denial-of-service attacks - as Gramps and Carl rot down so Gunnar lurches up.

Fwd: FOIL Request No. 2022-090560 - Larson
by Gunnar Larson 13 Oct '22

“We would like to receive any and all records, relating to NY-DFS' 2021 Apple Card Investigation. This is one part of a broader discussion we must have about equal credit access. On March 23, 2021, Ms. Linda Lacewell published NY-DFS' Findings on Apple Card and its Underwriter Goldman Sachs Bank. As the former Superintendent of NY- DFS, Ms. Lacewell's stone faced propaganda assured that Apple Card did not discriminate against women, while under Goldman Sachs management. The red flags started to appear when an authorized user drew attention to the following: A person who relies on a spouse's access to credit, and only accesses those accounts as an authorized user, may incorrectly believe they have the same credit profile as the spouse. We recently collated 61 highlights to the Report on Apple Card Investigation from March 2021: https://drive.google.com/file/d/1xH16OKyuXzB-MVqIznMWDE9w8RRdmZCw/view The Apple Card investigation was to assess women's access to equitable finance. The integrity of the Apple Card investigation must be rationally considered as flawed. We would like to receive any and all records of Ms. Linda Lacewell's (emails, texts, and similar) involvement with the 2021 Apple Card report. We would like to receive any and all records to NY-DFS association to evaluating Ms. Linda Lacewell's ability to score a report specific to the Apple Card's core subject of credit access for women. Finally, we would like to receive any and all records related to NY-DFS guidance on Interlocking Directorates ( https://www.dfs.ny.gov/apps_and_licensing/banks_and_trusts/other/Permission… rlocking_Directors_and_Officers), specific to Apple's Board of Directors and Goldman Sachs' Board of Directors.” ---------- Forwarded message --------- From: JeanBaptiste, Pascale (DFS) <Pascale.JeanBaptiste(a)dfs.ny.gov> Date: Wed, Oct 12, 2022, 9:17 PM Subject: FOIL Request No. 2022-090560 - Larson To: Gunnar Larson <g(a)xny.io> Cc: Garrett, Carmen (DFS) <Carmen.Garrett(a)dfs.ny.gov> Dear Gunnar Larson: Please see the attached determination in response to your FOIL request.

Dear DFS Records: Thank you for the update concerning, 2022-092039: “Bank.org demands any and all records concerning the Superintendent's said DFS role with Brex (Declaration on said disclosure form).” Expected due date: 10.12.22. Dear EXEC Records: We have the same FOIL request pending with your office (attached). Do you have any updates on this important Interlocking directorates type FOIL request? We are concerned that the Brex role has association with the PayPal Mafia. Thank you, Gunnar Gunnar Larson xNY.io - Bank.org 646-454-9107 On Wed, Oct 12, 2022, 9:19 AM <Edward.Meltzer(a)dfs.ny.gov> wrote: > Good morning, > > > > Attached please find correspondence from the NYS Department of Financial > Services, pertaining to your FOIL request. > > > > Thank you. > > Tracking Number:FOIL-2022-092039-018266 >

Re: Response to NY FOIL request FOIL-2022-090440-018156

Mr. Bogdan: We would like to appeal this FOIL determination. Specific to scholarships in Africa, Goldman Sachs has issued advertisements as principal funder of Africa's largest online University. DFS having no records associated with 'one of the world's largest minority scholarship programs...' that is funded out of New York would allude to willful negligence on behalf of New York's financial regulators. Recently, we received a FOIL denial for any and all records related to DFS' approach to obstruction of justice as part of the FOIL process. DFS responded, saying we are making "incoherent and general" records requests. So please let me clarify: As a Bill and Melinda Gates Scholar, I personally have an obligation to make sure our firm does not willfully ignore DFS having no records related to potentially the world's largest scholarship fraud funded out of New York. Warm regards, Gunnar Gunnar Larson xNY.io - Bank.org 646-454-9107 On Mon, Sep 19, 2022, 2:36 PM <George.Bogdan(a)dfs.ny.gov> wrote: > Dear Mr. Larson: > > My response to your FOIL concerning Goldman Sachs and interlocking > directorates is attached. > > Sincerely, > > George Bogdan > DFS Records Access Officer > > Tracking Number:FOIL-2022-090440-018156 >
