Happens all the time, especially on the phone. This tragedy happened when my daughter was trying to pull the phone, the screen rotated and as I tried to hold the phone my point finger hit the 'Mark forums read' button. I lost the unread mark for over two weeks of forum posts and discussions I was planning to finally engage on.
Also, when you are on a subforum the button is dangerously close above the numbers of pages, on top (all this applies to the original silver theme)
Maybe there's a way to undo the final command and the instances, but besides that I think a confirmation box would solve most problems.
I didn't find the right solution from the internet.
