u/Puppet--

I feel like I've seen a post about this before, but I'm going to post about it anyway.

People replacing em dashes with hyphens isn't the worst part. The worst part is then they don't put a space before it, but do after it. For example:

"That's not his ball- it's her ball".

It should be an em dash. In British English, there should be spaces on both sides. In American English, there should be no spaces.

It drives me insane.

Edit: Reading back on my example, a semicolon would be better, but you get the point.
