Yes.

jcl, try this in Google Chrome:

1) Shift + Ctrl + Delete. This opens "Clear Browsing Data".
2) "Advanced" Tab
3) Time range: "all time"
4) Check "Cookies and other site data"
5) Click "Clear Data"
6) Close browser and open it again
7) Go to Zorro User Forum
8) Click on this thread ("Ads?!?!?!?!?!?!?")
9) Click anywhere in the web page... This should induce the pop-up.
10) Right-click anywhere on the web page and click "Inspect"
11) Click on the "Sources" tab
12) Now take a look at the tree - there should be two offensive javascripts loaded:

top -> om.qqtx.me -> jquery.jscroll.min.js
top -> om.qqtx.me -> jquery.jscroll.min.js?timestamp=[etc.]

I have identified these two scripts as the culprit. If I explicitly block these scripts, I get no pop-ups.

The site has repeated this behavior just now.
