4chan's Anti-VPN Technology Chud 04/29/25 (Tue) 02:20:20 №11794 [Quote]

Curious.

I'm dying to see how this was implemented. I didn't see it in the official release, and it's not user data so it should have been released with the rest of the source.

The code leak was a ploy to trick people into thinking it's benign and emails are hashed.

They want to collect our emails and trolltrace anons.

There have been several threads already taunting anons along the lines of what if everything you posted on 4chan was made public.

That seems totally plausible given the lack of anything useful being revealed. The site had conspicuous immunity during the "cancel culture" phase. This would of course also implicate this website.

I'll bet it's just an anti-spam list that joons are EXTREMELY autistic about

There is no adept anti-VPN technology, just 10+ GB of IP addresses that accumulated in the last 20 years.

>just a list of IPs
The detection of new networks was far too quick: about 2-weeks on average after visiting 4chan a few times.

I skimmed that PHP file that was released and there is absolutely nothing regarding anti-VPN logic. Why was this omitted from the leak?

Look up ASN number of the IP. If it belongs to Datacenter it's sus.

Nigga, its not some super high tech and the fact that i have been posting from VPNs when I ban evade which happens a lot is proof. Their whole anti VPN tech is just banning all the IPs of VPNs when people bann evade but do not clear cookies. 4chan's Bann Database is 10 GB big and contains only text. Go make a txt file and see its size: for a file to be 10GB it needs to have millions of entries.

wanna know why is it omitted? because it does not exists. Jannies ban for everything and ban evasion happens so frequently and so autistically that anon on 4chan use weaponized autism to just be able to post. My last bann was yesterday for 24 hours on /g/ and I already have bann evaded using a local university free "private" VPN. While I of course know how to bann evade and not get caught others probably do not delete cookies or post the same thing they were banned for.

OK where is that implemented in the leaked code? Source (code)?
