in the notice text area of a forum, there’s message:
“This forum contains xxx topics, and was last updated by”
and there’s an avatar before the user, how to remove that?

also, that’s the case for a topic, how to remove that?
“This topic contains xxx replies, has xxx voice, and was last updated by”

BTW,
I managed to remove some avatars in other areas through this:

.widget_display_topics  .bbp-author-avatar { display: none ! important; }
.bbp-topic-started-by .bbp-author-avatar { display: none ! important; }
.bbp-topic-freshness-author  .bbp-author-avatar { display: none ! important; }
<code></code>

i think this does what you want.

add_filter( 'bbp_get_single_forum_description', 'ja_return_blank' );
add_filter( 'bbp_get_single_topic_description', 'ja_return_blank' );
function ja_return_blank() {
    return '';
}

it works, thanks a lot. BTW, how to remove the avatar only (keep the message)?
also, there’s also an avatar before the user if a reply was modified by the user, it will say:
“This topic was modified 3 days, 23 hours ago by …”
how to remove the avatar?

use this CSS

#bbpress-forums ul.bbp-reply-revision-log img.avatar,
 #bbpress-forums ul.bbp-topic-revision-log img.avatar,
 #bbpress-forums div.bbp-template-notice img.avatar {
  display: none!important;
}
