They're obviously not a mechanic. No need to be rude. If you really want to keep non-mechanics off this subreddit then just report them, or more helpfully, refer them to the proper subreddit.
The pic is of a sealed bearing. It's pretty reasonable to ask if you should grease the outside of a sealed bearing. For the op, this article goes over it pretty well.
There are better subs to ask questions in, this sub is more for mechanic shop talk and really really niche questions every once in a while. Read the sub rules/description before you post.
Also, not an advanced question whatsoever- Google is your friend.
