(I'm probably not going to join the server, if you are one of the
toxic owners looking to see if I joined to ban me. np saved you time.)
I read the Discord Terms of Services multiple times, and that is not considered DM advertising. You can report people for DM advertising, and they will disable DM advertisers' accounts. If they don't ban the user for your definition of "DM advertising", it's not considered DM advertising. At most, they'll say just block them.
If you really believe that's DM advertising, try reporting them yourself: https://support.discord.com/hc/en-us/requests/new?ticket_form_id=360000029731 (use message links, not images, they won't accept images)
They won't disable "Naman"'s account (in this case), because it is not considered DM advertising.
just for people who own that host to read this
