Possibly blocked by CloudFlare for submitting a reply with Objective-C code

I tried to post a followup to a previous reply of my own on a thread asking whether it was possible to rename an audio device, and when I attempted to preview my reply, I got the following message from Cloudflare:

While I cannot post the offending content here for obvious reasons, I can send a markdown file with it via E-mail if an administrator contacts me to verify that there's nothing fishy in the reply that I was composing.
