Our users often ask: How can I filter posts containing third-party links from my feed/channel?

If your goal is not to delete entire posts, but only to remove or replace links in them, read this article.

Method 1: Remove all posts containing links

This problem can be solved by creating filters using a regular expression. These filters will check for any clickable links (<a> tags and links beginning with http and https).

Open the forwarding you want to apply filtering to;
‍In the list of settings, find "Filters";
Create 2 filters :

Filter type: _🔍_{Regular expression}
Value (copy and paste): _{.*<a[^<]+</a>.*}
Uncheck the box to the left of the magnifying glass icon

‍

Filter type: _🔍_{Regular expression}
Value (copy and paste): _{.*https?:\/\/\S+.*}
Uncheck the box to the left of the magnifying glass icon

Create a filter 🔍 By regular expression
‍
‍

Enter the value: uncheck the box and save the changes
‍
‍

Create a second filter .*https?:\/\/\S+.*

‍

For @username (not added by the bot):

Filter type: _🔍_{Regular expression}
Value (copy and paste): .*@([a-zA-Z0-9=&_\-]+).*
Uncheck the box to the left of the magnifying glass icon
‍

‍

Method 2 needs the /track command, and that one runs inside the bot itself.Для Способа 2 понадобится команда /track — она работает в самом боте.

Method 2: Remove posts with a specific link

First, enable processing report generation. Then, you need to see how this link appears to the bot.

In a chat with @junction_bot , send the _{/track command}and a link to the original message.
Open The source code of the message sent by the bot. This is text containing special HTML markup characters responsible for message formatting.
Find the fragment with the link (for example <a href=...>) and copy it.
Go to Forwarding Settings > Filters
Create a new filter 🎯 By text match and paste the copied fragment with the link.
Uncheck the box to the left of the magnifying glass icon and save.
