that is entirely intentional – it lets keymasters see IP addresses to spot people who might post under several names.

you could hide it with css

.bbp-reply-ip {
display : none !important ;
}

or amend line 512 of loop-single-reply

create a directory on your theme called ‘bbpress’
ie wp-content/themes/%your-theme-name%/bbpress

where %your-theme-name% is the name of your theme

find
wp-content/plugins/bbpress/templates/default/bbpress/loop-single-reply.php
Make a copy of this file, and put in in the directory called bbpress that you created above, so you end up with
wp-content/themes/%your-theme-name%/bbpress/loop-single-reply.php
bbPress will now use this template instead of the original

then take out line 51 – you may also need to do this to loop-single-topic

or use a filter to get rid of it

function remove_ip () {
$author_ip = '' ;
return $author_ip ;
}

add_filter( 'bbp_get_author_ip', 'remove_ip');
