HiveWatchers is doing a wonderful job and really helping the community become more robust and reliable. They have been doing a commendable job since the start.
I am unaware of any technicalities behind the HW But IMO, manual strategy of blacklisting won't go far in Future. We just have to be prepared for at least 10K to 50K daily active users.
A better way could be removing most of the the manual work and focussing on decentralised blacklist as proposed earlier and help the team deliver it fast.
