Congestion Attacks in Payment Channel Networks

[ABCbits]

I was looking for few papers on arXiv and found very interesting paper with title "Congestion Attacks in Payment Channel Networks"^[1] and just submitted 2 days ago.
They mention 2 possible attack which are :
1. Attacking whole network by relaying a transaction to the attacker himself. Surprisingly, similar method is suggested to improve user's privacy^[2]
2. Isolate a single node/hub by creating multiple payment request through attacked node/hub (i don't really understand this part)

What do you think?

A newbie has posted not long ago Medium link on this same subject. It may worth a read, I don't know, I still didn't completely understand it.
