yep, since 97. Last festival was 2017, so some small change is possible. There was a time when people started leaving far more stuff, including everything. Tents, cases of beer, clothes. It was shameful. You can't single out Gazebos. For people who took them home, they made a nice shady spot or even dry spot. I hope that, if we have a hot one, we don't see the medical people over run. Heat stroke is no fun. Why should people who did it right suffer? Clearly they shouldn't, but the enviromental side makes a great argument for not buying in more camping space.
