Free University Brighton has been working since 2012 to provide an alternative and for the last five years we’ve been running ‘freegrees’. These are University level courses, open to all regardless of qualification. Our courses range from 4 week long introductory courses aimed at First Years (people who have never been to University before) to 12-week long Humanities, Social Sciences and Philosophy courses that rival anything in a ‘traditional’ University. We do this all with no money exchanged anywhere - no fees, no debt.
Shut up and show us the courses.

Other mentions of "Denis Petrov":
In 2025, the FBI got interested in the creator of the website due to its news paywall circumvention usage, and the dude started going nuts, coming after anyone who had previously investigated him with OSINT, e.g. the author of gyrovague.com and Ciro Santilli:
Later on in 2026 Wikipedia banned archive.today links because it had DDoS'ed Wikipedia and tampered with snapshots: arstechnica.com/tech-policy/2026/02/wikipedia-bans-archive-today-after-site-executed-ddos-and-altered-web-captures/ The dude had gone completely unhinged, destroying everything he built.
Sponsor updates Updated 2025-07-16

Updates Updated 2025-07-16
This section contains the a list of cool things Ciro Santilli has been up to in chronological order, including small quick ones. Many/most of those are also posted on Ciro Santilli's accounts such as:

ProtonMail asks for login every time in the browser Updated 2025-07-16
It is fucking annoying!

- protonmail.uservoice.com/forums/945460-general-ideas/suggestions/48228635-mail-proton-me-should-automatically-login-to-last
Not just on browser close. Whenever Ciro Santilli pastes proton.me/ on the browser bar and click enter. Chromium 123.
More precisely: pasting mail.proton.me on the browser bar redirects to account.proton.me/switch each time. From there, selecting different accounts leads to different mail.proton.me/u/<UID>/inbox, e.g. mail.proton.me/u/41/inbox is my main one. If I paste mail.proton.me/u/41/inbox on the browser, then it works directly.

Golden (wiki) Updated 2025-07-16
April 2024: merged with some fraud protection thing, is it sill a Wiki? Unclear, seem sto have lost that aspect: twitter.com/judegomila/status/1783028847983956430
techcrunch.com/2019/04/30/golden-launch/Exactly! Deletionism on Wikipedia is so sad, and especially for companies. In particular e.g. Ciro Santilli tried to create a page for PsiQuantum, and it got reverted... and now golden has one of the largest Google hits for it: golden.com/wiki/PsiQuantum-PBDGXRA
To state the obvious: Wikipedia is an incredibly useful website, but Gomila pointed out that notable companies and technologies like SV Angel, Benchling, Lisk and Urbit don’t currently have entries. Part of the problem is what he called Wikipedia’s “arbitrary notability threshold,” where pages are deleted for not being notable enough. (This is also what happened years ago to the Wikipedia page about yours truly — which I swear I didn’t write myself.)
TODO how do they do moderation?
As of April 2024Asked at: twitter.com/cirosantilli/status/1777250258235302233 Their last tweets were from August 2023, so maybe they just silently shutdown? Their name is too generic and hard to search for efficiently...
Login is currently disabled.
They do have knowledge graph built-in which is cool.
There are unlisted articles, also show them or only show them.
