Is feeding drunk toxic?

Basically the topic. Just had a player who was playing drunk and fed hard. He admitted that he was drunk and that is was a bad idea to play, but I'm unsure if it's behaviour that should be reported/punished. On the one hand he knew before he started, that he would not be able to perform well and that he would most likely waste the time of multiple other players. On the other hand, he (hopefully) never intended to feed.
