Nevermind, I just read the FAQ.
https://4chan.org/faq#banappeal>Can I appeal my ban?>Yes. Use the embedded appeal tool on the banned page to appeal your ban. Read the entire banned page carefully before disputing your ban. Note that some bans require you sit out for a few days before allowing you to appeal the ban. If you believe an error has been made, or you are being mistakenly affected by a ban meant for somebody else, contact a moderator on IRC at #4chan @ Rizon. Moderators are available to assist users with bans and technical issues on the website. PM a moderator (operators in the channel denoted by @ or % symbols before their name) with all relevant information, including your IP address if banned. Please note: this is a public channel, everything you say here can be logged and repeated elsewhere. Do not release your personal information in the channel!Does it need to be a paragraph long, or can I just say what I wrote in the OP?
