I think I would like to reserve that for people who are active in the group.
Check out the rules
I have an option called citizenship
There is an activity requirement. I have not really been enforsing that, mostly have it there so that if I ever do get in a situation like BABA was in where I have to get rid of members to stay under 1,000 then I will have a basis for selecting members to delete.
But if you want to advertise your group, here is what I will do.
I will create a thread for advertising your group. But anyone who posts there before they apply for citizenship and fulfills the activity requirement, then they will get a warning and their message deleted.
If you want a permium spot in the index with a link then you have to do twice the activity required for citizenship
If a group supports attacking other groups, supports racism or other prejudices or promotes bullying or any other inappropriate activity they will be denied the right to advertise. I retain the right to deny any group advertising.
Sound OK?
