Is there a way for the other person to know if I search my ID on Kakaotalk?

pu1. If I search for the ID, I think it'll come up as a recommended friend, but I'm not sure

OK

pu2. If you register, it'll probably come up as a recommended friend It won't come up just by searching the ID

OK

pu3. Even if you don't register as a friend, it appears as a recommended friend, so I think it's a way to recommend friends who are similarly connected. I don't know if you'll use ID search, but there's no way that the other person can know just by searching the ID

OK
