blog removed from planet

[Luca Ferrari]

Dear web team,
I've seen that my blog has been removed from the planet
<https://invent.kde.org/websites/planet-kde-org/-/blob/master/planet.ini#L3856>
but I have not received any news about this.
While this can be fine, since I'm more a KDE user than a contributor
(except for presenting it in my classes), I would like to know the
reason so to fix, for the future, my blog.

Thanks,
Luca
