So, the syntax is:

!truegaming@kbin.social

That yields:

!truegaming@kbin.social

On lemmy instances, the visible text is “!truegaming@kbin.social”.

On kbin instances – and I really think that this should be changed – the instance renders the visible text to be “!truegaming”.

Both still create a valid link to it if you use the syntax with the appended “@instancename”. Just on kbin, you don’t get to see what someone actually typed. You can hover the mouse over it to see the instance to which it’s linking.
