Help with banning from guild (keep being auto re-invited)

Hi,
Ive banned the same person 3 times and they end up back in the guild.
Its saying they are re-invited by me.
I have them in my Guild roster manager ban list.
To ban then im going into guild and communities, then remove player and checking the ban box.
So that both banning in guild box and GRM
This is 3 bans over 3 days yet its saying the ban is today.
Any help pls (see pics)

If you’re posting the guild link in trade or whatever you’re effectively re-inviting them.

The link bypasses the application process.

Oh that makes sense , thanks Elvenbane,
Is there a way to set it so i have to click to accept?
I used to have “guild applicant tracker” and id either click in that or have to go to
" j>roster>applicants" and manually approve.
Since reinstalling wow guild app tracker wont pop up

No. Blizz determines how it works.

Ok thanks
