You can use <span></span> to surround the linkified domain, rather than inserting it in the middle. This is useful when talking about companies and other proper names with dots in their names, like itch.io.
For example, if you just type itch.io in the Markdown editor, it will be linkified: itch.io
But you can instead type <span>itch.io</span>, and then it won’t be linkified: itch.io
You don’t have to insert <span></span> in the middle of the link, like this, itch<span></span>.io but that also works: itch.io
(It would be nice if @precessor or a moderator could change the “
Solution” check to this answer instead of the currently selected solution; the old solution worked in 2016, but no longer works today.)
