@AB de Royse777, I don't know if you have a means of tracking who has been wearing r7 avatar, text and signature for a long time and also a way of knowing those you have hired previously in paid campaigns that ended. There are those who have not benefited from your paid campaign before.
I suggest that those who got into paid campaign from here should be removed from the spreadsheet, and when the paid campaign ends and they rejoin here, they should be placed at the base of spreadsheet. By this, r7 older participants who has never joined your paid campaign could form a priority.
Don't take offence, just my 1 cent which could also be disregarded.
