BuddyPress.org

It depends on which template pack you are using.

For Legacy, it is this template file:
buddypress\bp-templates\bp-legacy\buddypress\members\register.php

Overload that template by copying it to a directory that you create in your child-theme:
buddypress\members\ and make your changes.

If you are using Nouveau, it is more difficult. This is the file:
buddypress\bp-templates\bp-nouveau\includes\functions.php
It is not a template file, so your choices are:
1. hack the file and redo the hack every time you update BP – not recommended
2. use a language translator
3. write a filter function

function kimo_change_nouveau_string( $array ) {

	$array['request-details']['message'] = "This is your custom message";

	return $array;

}
add_filter( 'bp_nouveau_feedback_messages', 'kimo_change_nouveau_string', 20, 1 );

Paste the function in your theme/functions.php or in bp-custom.php
Test to make sure it is working.
Then adjust the message to your liking.

@mbigler
– What have you done so far to resolve the issue? What theme are you using? Have you changed to a default theme to see if that resolves the issue? Have tried deactivating other plugins to see if there are conflicts preventing account deletion?
– Where is BuddyPress activated in your multisite, in the main site or in subsite/subdomain? Have you enabled MULTIBLOG or is it basic BP in multisite?

Help us help you by providing more info about your setup. https://buddypress.org/support/topic/when-asking-for-support-2/
