It's a reasonable assumption that a person registering for an event 5
times in quick succession meant to only go once. It's also a nice UX
trick to use JavaScript to grey out the form's submit button once it
has been clicked. Or you go to a placeholder site while you process
the data. Or send the data off to a worker threat, and redirect the
user to another page, telling them their request is being processed
and will show up soon.

(Ah, how soon!) they forget
When I've moved on to some other place,
There may be one or two,
When I've played and passed through,
Who'll remember my song or my face.
