That seems like a good idea to me. You can report "urgent abuse" to Support.
At present, getting past the Support AI for reporting serious abuse requires you to input a member username.
You can use the username of whoever recommended the club to you.
I assume you get a chance to write a description of the abuse you have seen (but I haven't actually tried it because it warns about not missing the form.)
I sometimes get invites to clubs, which have an inappropriate name or photo, or both. So i disabled club invites. Yet, some creeps DM me to "check" out their clubs, which contain obscene stuff. I report these pervers, and I want to know if there is a way to report such inappropriate clubs.
