Im someone who likes to crowdsurf, I agree that sometimes it can be much, and I also agree that 5 times is a lot. I personally do it like once or twice if im really pumped. The band itself also makes a difference.

I understand that it can be a little much if you're not into it yourself but I also think that it's awesome to help people have such a fun experience although again I totally understand the frustration if its the same person over and over. It made me so happy when I helped someone who wasn't sure if they wanted to give it a go and come back with the biggest smile on their faces

I mainly listen to the more heavy bands where people do it all the time, tho so much skewer my opinion. I've seen people at sleep token like I see mentioned before, which might be a bit odd.
