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). 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)
