Splatoon

Splatoon is a third-person shooter game made by Nintendo.

You could make Splatoon related Miiverse posts within Inkopolis plaza via the mailbox in next to the Inkopolis tower.The majority of these posts in Inkopolis Plaza would show up over the heads of other peoples inkling avatars that would walk around the plaza. Posts could also show up on the sides of buildings in the plaza as graffiti. In battle stages, Miiverse posts showed up on walls, buildings, etc as graffiti as well. You could "Yeah!" these Miiverse posts within the game too.

Ever since Miiverse was removed Miiverse posts in Inkopolis plaza have become non-existent. The Inkling avatars that walk around Inkopolis plaza are all default and don't have any posts displayed above their heads when you walk up to them. Miiverse posts in battle stages have been replaced with default pre-made Nintendo posts.

In Splatoon 2 however, you can make posts that are similar to Splatoon 1's Miiverse posts. The posts in Splatoon 2 are not Miiverse posts but are instead built into the game itself. But you have to have either a Twitter and/or Facebook account linked to your Nintendo Switch account to make posts. Other than that the Splatoon 2 posts basically work the same as Splatoon 1's old Miiverse posts.
