Help with 閲覧できるの投稿


In [this](https://www3.nhk.or.jp/news/html/20230705/amp/k10014119301000.html)
nhk article about the recent twitter restrictions, I came across this passage:

> **閲覧できるの投稿** の数は1日あたり、▽認証済みアカウントでは6000件、 ▽認証されていないアカウントは600件、
> ▽作成されたばかりの認証されていないアカウントは300件までとしました。

really imagine why the choice was made to insert a の here when it didn't seem
necessary.

My best guess is that it's making a nominalised topic out of 閲覧できる, with a
pause implied after it, meaning something like: "As for what one can browse,
the number of posts per day is..."
