Also, would it be possible to have a notification before opening links, sort of "are you sure you want to b redirected to..."
This would prevent inadvertently clicking on links, especially when you're on mobile.
Totally support this, I access Bitcointalk mostly with a mobile phone and I can testify that there are times when I want to scroll and I mistakenly touch a link and it opens right away without any kind or form of warning, and when this happens, I have to press the back button to return back to the page I was before.
There are times too when If I want to zoom the content of the page to enable me see the words clearly, the above happens too.
Exactly. On mobile platforms you can accidentally activate hidden links upon random tapping on blank spaces. That's a lot easier to abuse than on a desktop computer. But this is unfortunately true for all websites as well.
I personally support the idea of having a notification or pop-up for all external links on the forum.
