Don't loose your cool, stay lose.

Why are so many people writing "loose" instead of "lose" and vice versa? I see it everyday in comment sections all over. Are they lazy, stupid or something else? I automatically think their entire post is worthless when I see that. Maybe censor bots are changing the spelling to make people look stupid and therefore their comments are stupid? If I was working that side of the street I would consider it a good tool. Make your enemy look stupid.
