You use Hacker News, you don't fall in to my teen category. :) (That's a compliment.)

Have a look at some of the sites here if you have time: rev.iew.me/users & you'll see what I mean.

For the record, I agree, code shouldn't have to come with a warning label; but I have seen many a site taken taken down by similarly bad code. I do my very best to help these youngsters where I can, because I was in their position once too. (Hence why I am here, to learn more and be able to offer more help to those who don't know so much.)
