Fix the Boards profile webpage on certain players' accounts

Why is it that a bunch of them has either no records or has the 404 Error page when checking their Boards profile?

Here are a few examples, and a reminder that I am not posting this thread as a "Naming & Shaming", as I have nothing against them, except excuse my "blunt & possibly rude" comments on them:

Best Ekko NA

https://boards.na.leagueoflegends.com/en/player/NA/Best%20Ekko%20NA?content_type=all

His profile says "He hasn't used Boards" but yet:

https://boards.na.leagueoflegends.com/en/c/skin-champion-concepts/AHjOO3Er-suggestion-new-rune-to-replace-grasp-of-the-undying

He does.

Luxkataiana

This is his post;

And this is his "404 error" profile, even though my Internet is fine.

Can we get a possible fix on this please?
