The crypto recovery scammer is really brave since he send his coins to Binance.
So this is a Binance BTC wallet?
That address mostly send the coins to
35gQshZJnTGVGM97pj2arQ9P5rPNAsMEto and then 35gQshZJnTGVGM97pj2arQ9P5rPNAsMEto send to Binance deposit address.
Can you tell if a lot of people have deposited money into his/her account?
No one can verify if different address is controlled by different person, but the fact there are many different addresses send the coins to this scammer.
Since you're not one of the victim and there's no proof if he really a scammer, I don't think there's need to take further action...
