It seems likes this is mostly an issue of scale, in well-traveled areas where lots of people go it's not going to make a lot of difference, while remote areas that could possibly see lots of sudden traffic, it would not be a good thing.
Also was one to be an "outdoor influencer" with thousands and thousands of followers rather than an average person, the effects could be that much more severe.
On the one hand, there’s the notion that posting content on the outdoors inspires others to get outside (see: #OptOutside, et al.). On the other, there’s the very real fear that posting photos of hidden hikes and hot springs invites an influx of visitors these places lack the resources to handle.
Geotagging can also get specific, and that’s where the real issues start. “We’re having a lot of problems with people geotagging hidden or sensitive places,” Boué said, adding that these places don’t always have the infrastructure to handle a lot of new visitors.
There are any number of small specific things in the outdoors that are preserved because not many people know about them, geotagging hurts that preservation.
