Chess960 player: How can I best use my 400 follow limit?

I use my follow list for people who seem to play a lot of 9LX and who are not too high in rating so I can challenge them/challenge them again and so I don't have to create challenges. I didn't reach 400 follow yet, but well yeah I've read about this 400 limit, soooo... 1. Question: So how can I best use this 400-max follow list? Well I guess with the limit I'd follow those who predominantly play 9LX instead of just anyone who plays a lot even if they play standard more (I guess I didn't expect there would be so many 9LX players, hehe!) 2. Question: Or perhaps there's actually no need to use follow list in this way because we hope/expect those 9LX people will be in either favourite opponents list or some 9LX group like as follows? https://lichess.org/team/chess960 https://lichess.org/team/fischer-random-chess-center 3. Request: Still...going through the list in the groups entails having to spend more time looking since I'll still have to process if the rating fits. If I follow 350 people, then maybe only like 20 (around 5%) will be online and then out of those 20 maybe only 1 will accept(/modify) my challenge. So I hope that the follower limit could be increased so I could have more options...Or well I guess there's always the groups...
