Hi Geoff,
Thank you for the question.

Please visit Dashboard->MediaPress->Settings->BuddyPress and disable the section for automatically adding to activity.

Hi Geoff,
Thank you for the reply and the clarification.

The media/gallery comments are internally activity comment/reply. Do you want to disable users from commenting the gallery/media? Otherwise, We can exclude it from main activity stream(by type) and still keep the commenting functionality.

Hi Geoff,
Thank you for your patience.

Please put this code in bp-custom.php

/**
 * Filters out media comment from activity stream.
 */
add_filter( 'bp_after_has_activities_parse_args', function ( $args ) {

	if ( isset( $_REQUEST['action'] ) && 'mpp_fetch_activity_media' == $_REQUEST['action'] ) {
		return $args;
	}

	if ( function_exists( 'mpp_is_single_media' ) && mpp_is_single_media() ) {
		return $args;
	}

	$filters   = isset  ( $args['meta_query'] ) ? (array) $args['meta_query'] : array();
	$filters[] = array(
		'key'     => '_mpp_activity_type',
		'compare' => '!=',
		'value'   => 'media_comment'
	);

	$args['meta_query'] = $filters;

	return $args;
} );

It should resolve the issue. Please let me know if it works or not?

Thank you
