What's the etiquette of doing or not doing this?

I went on a hike yesterday and saw over a dozen different tree branches with pink plastic tape marking who knows what. Part of me wanted to remove them and part of me wanted to leave it because who knows what it indicates. I could tell some of it marked a random turn off point because I could see more tape down into the woods off trail.

So what would you do? Leave it? Take it down? Does it matter if you're in a wilderness area vs a national forest?
