Maybe it's a Windows thing to want to have "warnings", but the Linux way is to do what the user wants, instantly. Asking for confirmation all the time only means people click it without reading, while it's much better to think about your actions before you do them.
Well, I guess you are more fond of Linux OS than Windows, however, we are talking about mobile phones here, and almost 98% of people use mobile phones with touchscreens. So, when we are accessing the forum or doing anything in general on a PC or a laptop, the odds of clicking things by mistake are extremely low, but when we are using devices with touchscreens, the odds of unintentional touches or clicks tend to be higher.
So, even though my suggestion isn't only for mobile phone users, it will provide more convenience for people accessing the forum on a mobile phone. Since the forum isn't very mobile-friendly, small additions such as this one could be useful.
It's just my opinion. Yours differs from mine, and that's a normal thing.
