Please take a look at the attached screenshot made in our FreshDesk Support Portal.
When an unlogged visitor clicks on Yes or No below an article, it changes the article modification date, while this date must be changed only in case its content is modified by the author/administrator.
Please fix this bug.
First off, apologies for not attending to this post much earlier.
I totally understand your point and hence let me pass this to my team and see if we can modify this current behavior.
Will surely keep you posted on the same, Alex.
We're really sorry that it took us a really long time to respond back to this post. The behaviour is no longer in existence and the last modified changes only when the Admin/Agent changes the article properties.
