The link at the bottom redirects you to a Hubski website with an embedded iframe with same Kiwi IRC page. It was a different domain and these are checked and blocked because most of the ads use iframes for positioning on the website. iframe can be imagined as a separate 'tab' within opened website, just like YouTube videos are embedded on Hubski. It was working on direct link because it was not an iframe, it was a whole page on same domain.
In NoScript options you can do this:
1. Open NoScript options
2. Go to Whitelist tab
3. Add both "kiwiirc.com" and "hubski.com" as whitelisted domains
and it should work from Hubski!
