Ban evasion

Some notes on ban evasion. A good chunk of this article is taken from old ‘arty threads and posts on this topic

Resetting your Router

If you wish to reset your router, you should first check if your IP address is static or dynamic. To see this, go to this website and click on your IPv4 address. If the IPv4 address is listed as "Not detected," you can lookup your IPV6 address instead, although note that virtually all imageboards use your IPv4 address (this shouldn't matter though for detecting if your ip is static or dynamic). The website will then tell you if your IP address is "likely static" or "likely dynamic." If your IP address is static, resetting your router will not work, as static IP addresses do not change.

In lieu of resetting your router, you may also spoof your router's WAN MAC address if you router is capable of doing so; this typically forces your ISP to provide a new IP address if it is dynamic.

FAQ

>I'm still banned despite switching proxies

Clear your cookies. The 4chan_pass cookie is used to identify ban evaders.

>How does 4chan block so many IPs?

They use a paid API known as Blockscript (https://www.blocked.com / https://archive.today/5a9BO). It blocks IPs considered to be abusive, such as IPs from datacenters, VPNs, Tor nodes, free proxies, etc.

>Why doesn't my post go through sometimes?

This depends on a variety of factors.

It could be your user-agent, or your file is secretly hashbanned, or the flood filter is on.

If 3 threads/replies are posted within a short period of time by users with different IPs and 4chan_pass cookies with a very little amount of posts attached to them (aka 'empty' 4chan_pass cookies), then the flood filter activates. It lasts exactly 5 minutes.

4chan compares your user-agent with what your TLS fingerprint says. e.g. If you have a Chrome TLS fingerprint, but your user-agent says you're using Firefox, this is an immediate redflag and your post doesn't go through. Use only user-agents that would fit your browser type.

On Firefox, you can create a dedicated Firefox profile just for shitposting (about:profiles) with this extension if need be https://addons.mozilla.org/en-US/firefox/addon/user-agent-string-switcher

Ban evasion on altchans

Most altchans allow VPNs and datacenter IPs. Therefore, you can use just about whatever VPN you want (even Tor might work)
