You should worry about everything you interact with, not just text on some small Internet forum. After all, you could be the star of your own reality-tv Truman Show, and everything you see is made up for the benefit of a TV show that you're the star of, but aren't privity to? How do you know your mom and dad aren't just hired actors along with all the people you interact with? Maybe I'm secretly being paid by producers of a TV show to write this comment to provoke you into discovering the truth of your existence for the season finale?
