About 90% of the public Youtube spam I see on YT still follows this ultra-simple template: one person asks something on the "top comment", another one replies with a faux-legitimate message. The question is often "does anyone know how to pirate videos?", "...how to invest in crypto", "...how to get fake instagram followers", life coaches, etc. It's not really custom messages with special chars, it's something that I could detect by using Ctrl+F in the browser. It's not something they'd need special tools on their end to catch. The only thing that is changing is the name of the users. So yes, I'm gonna agree with GP that "the formats of the obvious spam" are super easy to detect.
