How do you invite to random people?

I get these invites to clubs from people I don't even know. Do they have an option to send the invite to every member, or is there some other way? Please leave how it works

Club admins can invite anyone who has their settings set to allow invitations.  Clubs can only invite 30 members/day.  Invitees have to be keyed in individually, so somebody thought to invite you.  If you don't want invitations, change your settings.

I rarely invite people to Peace Loving Chess Warriors through the "Invite Members" Chess.com way.  It is cold.  But we need new active members.  And with minimal work,  feeling hopeful,  I only need to type 3 letters like "hap" to see some members I don't know and invite them.  We are allowed 30 a day.  I would guess less than 1% accept.  It's better to make a connection to get a new member.  But I have tried New Clubs through random Invites, and am incredibly happy I joined some of them.

I invite daily players from the site charts. Proven players of daily games. Wouldn't call it random, but I don't know most of them either. Sooner or later I will invite you as well
