My guess is that their add-comment PHP script uses addslashes (or an equivalent) on the posted comment to prevent a SQL injection attack, but recent versions of PHP already do that by default for POST/GET/COOKIE data. The end result is that a mangled string gets stored in the database, hence the slashes everywhere. The edit-comment script does it correctly, so you can go back later and un-mangle it.
