The problem is hard as police is using various tactics to try to silence protestors. As mentioned they “can join and hone in on”. And once found physical protestors, they can beaten them up and then if circumstances allow, they could charge them as beaten up police instead etc. So far 1000+ arrest and as you seen many protestors are hurt - 4 eyes are lost ... etc.
The leaderless communities have to work out how to communicate. This is one of the attempts as LIHKG is ddosed during protest time. No doubt, they will try others. We will try until the five demands are met. (The last one is for the real elections as promised in joint declaration and basic laws.)
