Attacked by same player 3 minutes apart?

I was attacked by a player named DaNjErouSs 2 times in a row 3 minutes apart. First attack he lost, triggered traps, took out my champs then attacked me again 3 minutes later with all the same troops. He 1 starred me on the second attack. how is it possible to make multiple attacks on the same players base? Is this something new or a bug that is being exploited?

How many trophies do you have? If you're low, then it is very likely that he is leaving you without a shield to keep attacking you. It's not uncommon at all.

I am not sure about the bugs. However, if you happen to attach his village, a player can revenge again and again until the option is there in the inbox.
