It's an amateur and unhelpful message much like "delete your cookies".
With my filtering, the page is blocked from loading content from js.driftt.com and sentry.io, both of which are likely needed for the page to function and results in the same message. Blocking Scott Helme's report-uri.com won't affect the page. You can try looking up the names in both your local name service and one offering unfiltered resolution such as as Quad9's 9.9.9.10.
```
$ host js.driftt.com
js.driftt.com has address 0.0.0.0
js.driftt.com has IPv6 address ::
$ host js.driftt.com 9.9.9.10
Using domain server:
Name: 9.9.9.10
Address: 9.9.9.10#53
Aliases:
js.driftt.com is an alias for dl7g9llrghqi1.cloudfront.net.
