"Informative" Ratings

So, some of you might be aware of this, some of you might not, but in some very old threads, like from 2013, 2014, or maybe 2015, that are still up and active to this day, in the few first pages of those threads, and the first posts of that thread, aside from likes and agreements, you might have seen another rating called "Informative" given to a specific post from the first few pages of that old thread. I've been looking around and searching about this "Informative" rating for a little now, and by the looks of it and the members who have given this rate to a post, first of all, you have be an old member with atleast 5 years time of being logged in to your beamng account. and also it's not available for everybody, and it looks like its only available for the old members or some specific people, just like the "Staff Pick" Rating with the beamng icon witch is only made and is available for the beamng team, anyways, i wanted to know if it's possible to give that rating to a post or you have to have the condition for it. (like atleast being 5 years in beamng community or something else that im not aware of). im saying this because i believe performing this action and giving this rating is still possible. i have seen some fairly new threads that have been created from 2023 and up, and some posts in those new threads also have this "Informative" rating given to them, witch is also visible down the post like likes and agreements (it also shows up when you go to your profile and then to the "Post Ratings" section on the left section of your profile as a specific rating from the like and agreements.). i think it might have been a feature back in the day and now it might have taken and only some specific people have access to it or maybe it's a limited feature that you can only give out in specific time and thread or it's a secret feature or something like that... there could a lot of other theories of what this secret rating is and how you could give it to a post or something like that.
Here's a photo from it, if you dont know what it is:

Any ideas on this?

 

No clue at all, I really want someone to rate your post 'informative' though. Just to mess with you.

But seriously, no idea. Sorry.

 

Yeah the informative rating ended up being a child predator

 

I'm just here to balance out the profile picture ratio.

I mean, wait what's this now?

 

is this a /s, or are you saying it fr?

 

hes trolling as usual

 

Informative was removed along with Agree because it was used sarcastically to express the exact opposite, and to spam people.
Agree was added back after that controversy.
