It's not really important to the solution at all, basically just prints the line.
Dunno why it had to be obfuscated lmao, maybe to try and throw people off?

I actually did it for the people who didn't want to see spoilers or hints while watching the source code :))

Turns out I'm on Chrome Canary and they have all kinds of beta nightly shit for anti-xss going on and it's being a real nazi with me.
Firefox seems to let some stuff go through and a lot of the stuff I try /seems/ to work but I just don't get the alert.

EDIT: Now Firefox is letting my request go through but removing my code zzzz

EDIT2: I HAVE A WITNESS TO PROVE IM NOT A 100% RETARD

I HAD THE SOLUTION BEFORE BUT RAN INTO SOME PROBLEMS AND IM ONLY ABOUT 10-15% RETARDED

Haha nice! Mind sending me the vector?

Spoiler (Click to View)
This is the final hint since this is also a pretty big spoiler.

Succes 🤝

Update#2

Pretty darn close

Just a matter of removing some '"' ?

Not sure how that didn't trigger the filter. Mind sending your steps that you did in a pm

NOTE: Some of you managed to get an alert box by a hex vector. That's patched.

Take off the http at the front or put spaces in it.
And don't put the url of the site as it will contain your vector, just a screenshot is fine.

Cba to post pic, but nice challenge, had me a bit amused for a while! Probably vulnerable to more than one vector aswell.

What do you mean you tried to patch it? Are you just patching people's vectors they used? How is that fair if you are making it harder & harder lol ?

Because I want the vector to be identical as the one I had in mind. Faith's vector was good and so is hoodie's vector.
