Please stop "Request to join the ${team} group" mails to no-owner members

Hi, I frequently get mails from teams where I'm not an owner in the team and thus not able to do anything. I guess this is also true for other team members and should be stopped. Example:

Date: Mon, 11 Mar 2019 20:10:14 +0000
From: Debian GitLab <gitlab@salsa.debian.org>
To: tille@debian.org
Subject: Request to join the Debian Games group

Pedro Pena (https://salsa.debian.org/qbancoffee-guest) requested Developer access to the Debian Games group.

It would be nice if this could be stopped. I'm not ownder of the Debian Games group neither from several others I've got similar mails from in the past. Thank you for maintaining salsa, Andreas.
