There is one way to get the link, but it's harder. You have to click "answered by [user]" or "commented by [user', which is much more troublesome, especially if they are further activity following it. As such, having a "Share the post or comment" option is much more better and easier to link particular posts, especially when there's a lot of answers, comments, etc.
Smogon has one such feature. As such having this in PokemonDB would prove helpful a lot.
