In asking for a reply you've already done the first way. Hence, the third way doesn't exist ;)

It still exists and it pops up in notifications instead of having to go into your own profile and look at your history. It's a lot easier for the user. If you choose not to reply to those people to make it easier for them, that's on you. The maker of the thread should appreciate the bump and reply if he's around.
