Hi @cryptoassets ,
Thank you for the provided details. 
In the Redditly template and the Post page you mention above, we used a MultilineInput element to let you insert a comment. By default, this element allows inserting multiline text without auto-detecting when it’s a hyperlink or not. Generally, when we design our templates, we try to use integrated Bubble elements and free plugins.
If you would like, you can change this MultilineInput element with a text redactor, a more advanced solution to insert and process text. You can consider our Advanced Rich Text Editor Plugin, it has an option to auto-detect when it’s a hyperlink and converts it accordingly. Please check the plugin’s supporting documentation.
Also, there are many other free Bubble redactors that can be used, when customizing this template.
As well, please check this forum thread, you might find it useful: No clickable link in multiline input possible?
If you require any further information, feel free to contact us.
Best regards,
Zeroqode Support Team.
