In the other thread I thought about suggesting that to add an "X" you have to give a reason so a popup would appear giving a box to fill in. This way, an accidental click would be avoided since the popup would alert the individual, and people might know what the disagreement would be about. But then I realized that most people that actually add an "X" are already angry and having to type something in would probably anger them more, or result in lots of "Wrong" as the reason rather than something with some information. So I never posted the idea.
