When I was exploring the Fediverse, I found that a lot of websites’ authors set text-align: justify on <p>. I really wish people stop doing that.
The spacing between words becomes uneven and by most of the time the white space is just too wide. We call that River in typography. When you look at the paragraphs, the white space between lines, looks like a river running through text blocks. Not only it looks bad, but affect readability.
