Solution

echo 'if ($programname == "systemd" or $programname == "systemd-logind")'\ 
' and ($msg contains "Starting Session" or $msg contains "Started Session"'\
' or $msg contains "Created slice" or $msg contains "Starting user-"'\
' or $msg contains "New session" or $msg contains "Removed session")'\
' then stop'>/etc/rsyslog.d/ignore-systemd-session.conf

systemctl restart rsyslog

run it in the console to create a file with the settings to stop spam
