You can filter the activity stream on a certain page with something like this:

function bp_no_blog_comment_filter( $a, $activities ) {

global $bp;



/* Only run the filter on activity streams where you want blog comments filtered out. For example, the following will only filter them on the sitewide activity tab: */

if ( $bp->current_component != $bp->activity->slug )

return $activities;



/* Then filter out all the blog comments */

foreach( $activities->activities as $key => $activity ) {

if ( $activity->type == 'new_blog_comment' ) {

unset( $activities->activities[$key] );

$activities->total_activity_count = $activities->total_activity_count - 1;

$activities->activity_count = $activities->activity_count - 1;

}

}



/* Renumber the array keys to account for missing items */

$activities_new = array_values( $activities->activities );

$activities->activities = $activities_new;

return $activities;

}

add_action( 'bp_has_activities', 'bp_no_blog_comment_filter', 10, 2 );

Obviously you may want to tweak some of the details, but that’s the basic idea – the comments are still recorded to the stream, and still appear on the individual member streams.
