The people at HoopGurlz aren’t paid by anyone, in fact they’re lucky they get travel expenses reimbursed. I know because I worked for them for a few years. Some sites like Gold Star, ASGR, ProspectsNation, etc get revenue from coaches/schools that subscribe to get more in depth info on recruits. Heck, if there were any money to be made in scouting I’d be doing that rather than dragging myself to an office every week
There are sites the parents pay for like Hudl but I’m not aware that they do rankings
While IMG is a high profile school, it’s quite possible Kelis simply wasn’t seen much and it’s possible when she was seen, she had a bad game. It’s not like scouts are at every game at every tournament - they’re spread thin and simply can’t see all of the players enough to make a complete evaluation. That’s why I pretty much disregard rankings
