Of course, I had to check logblock, and it seems quite a few people have...

I simply must wonder: what compels everyone to open and close them? If you saw a trapdoor on a balloon in real life, would you just go opening and closing it willy nilly? One person even came to a trapdoor, closed it a few times, then came back a month later and closed it a few more times! Do they jump in and try to burn themselves to death? Are they looking for easter eggs? I must know!
Being scientifically minded, I decided to survey all of the balloons within the actual biomes. Here are the results (Not counting multiple entries, which there were plenty of on some, or the ones that I mistakenly closed when meaning to check logblock)
