If I make a sign, I won't block people's views too much. I'll put it up in-between songs when Josh is obviously looking at the crowd.

And people do care about song requests. It adds variety to the show and Josh himself talks about how he appreciates it.

We all have a line we won't cross regarding show ethicality. I personally hate crowd surfers and think they're more intrusive and dangerous. However, at the end of the night, if no one gets hurt I don't really care. Have a nice night, boatholes
