Yes, as my classmate said. If this is fake please tell me.

If there are any public posts about this, please tell me also. After all, I'm really not good at browsing historical materials.

If this is true, I wonder what'll happen if a person with negative rating upvote one of my post. Would my contribution increase a tiny? Or it wouldn't make any effort? Or my contribution would decrease instead?

Please tell me because I'm dumb.
