flycutlink.com: detection

[Novikov099]

Prerequisites

• I verified that this is not a filter list issue. Report any issues with filter lists or broken website functionality in the uAssets issue tracker.
• This is NOT a YouTube, Facebook or Twitch report. These sites MUST be reported by clicking their respective links.
• I performed a cursory search of the issue tracker to avoid opening a duplicate issue.
• The issue is not present after disabling uBO in the browser.
• I checked the documentation to understand that the issue I am reporting is not normal behavior.

I tried to reproduce the issue when...

• uBO is the only extension.
• using a new, unmodified browser profile.

Description

Greetings:

I have tried to download an NSFW video from a page that already had filters applied for its link shortener and it worked without problems, but for a week I have not been able to overcome its anti ublock detection, I tried with several filters from other websites and the result remains the same, the blocking banner jumps or the shortener counter stops. The link shortener that the page uses is flycutlink.com and apparently it is using new engineering in its detection.

A specific URL where the issue occurs.

https://flycutlink.com/4bPKzNF0O

Steps to Reproduce

1, The download button is tapped on the NSFW content page
2, The shortener should then show the button to solve the captcha
3, The captcha is resolved and after finishing its counter the link to the download host appears

Point 2 cannot be done because a ublock detection banner appears

Expected behavior

No banner should appear indicating that an blocks ads was detected; instead, the link shortener page should appear, asking you to solve the captcha and then redirecting you to the download host's link.

Actual behavior
