Jow Forums bug

guys, my team of professionals has found a bug on this website, if you try to post the following text your IP gets banned, but not really, it will just show the message "Your IP or IP range is blocked from accessing Jow Forums." (if you use 4chanX it'll be connection error)
This is the cursed message is in this message, because like I said it's impossible to post
pastebin.com/raw/jny8tudn
if you remove the semicolon though it posts fine.
It isn't like normal spamfilter stuff. How is this possible? If 4chans codebase was FLOSS we wouldn't have this issue.

You can't post certain bash commands, probably related to the semicolon. Some moron in the system somewhere is filtering this stuff as an incredibly crude block against some virus. Last thread claimed it was cloudflare doing it, not Jow Forums, but that seems unlikely.

is not;
can be posted fine

okay I boiled it down, you can't post the "shell" is not[semicolon] part

test;
shell;

not;

is this exploitable???

It's with something in the antispam. A few months ago I had an error that I needed help with and when I tried posting the logs here it would give the same message, so then I tried to upload it to pastebin and they also marked it as spam. Weird

in the irc they said it was cloudflare
