Like some sort of badge in the profile, or what would you have in mind?
Edit: you mean something like Xonotic's Player badges?
https://gitlab.com/xonotic/xonstat-badgesHmm... in Hubzilla it is probably possible by customizing your channel page (I turned that features off as it is very complex) but I don't think there is an easy way to do it right now.
Plugins between Friendica and Hubzilla used to be very similar, but since the recent change in Hubzilla to split them into addon and app (the latter are the ones accessible through that user-app interface) it must have become quite a bit more involved.
What exists is a very early "channel reputation" plugin for Hubzilla, but that is more to allow community moderation on public forums, i.e. users with a lot of likes and replies get some sort of invisible points with allow them to use more features etc. It's kind of a spam and quality assurance tool.
Edit2: I am actually also interested in something like that as I would like to add such XMPP badges to the profile/channel:
