Top Rope filter question

When you use the top rope filter in mountain project, what exactly is that telling you about the route? Can't you set up a top rope on any 2 bolt anchor? Is it saying that the route is better suited for top rope because it doesn't have any overhanging rock or anything that would make top rope a bad idea for your rope's lifespan?

From my understanding it has been designsted by whoever put it on MP as a TR route. So the longevity of your rope is not guaranteed, nor is a two bolt anchor, but there will be a way to set up a line.

The information you're looking for is usually on the route page or the crag page.

I just looked at the editing fields for a page I submitted, and here is all the designation itself means: "you can set up a TR without leading the route."

The details are left to the contributors.

I've seen quite a few routes where it says TR but their anchors are all unreachable without rapping from above. 

As others have said, the filter would pick any routes that the person adding the routes to the database designated as “top-rope”.

They could be sport or gear routes with easy access to the top. But imo Most of the routes that are entered into database as toprope are the routes that are TR only. Sometimes the routes are in a state park, etc, where the bolting is not allowed, and there is no way to protect the climb with gear, but you can access the top of the cliff and set up anchors off the trees. 

The only way to know for sure would be to read the details for individual routes you picked up with that filter. 

Be careful when using that filter though!....it could suck you into a universe where you eventually sit around with folks like those pictured below (found recently in certain crags in Ontario and Illinois) where you debate the merits of adding bolts every 3-5 feet to avoid the pain and shame and hassle of top roping vs “leading” like real climbers. Wanna be like the hard guys in the gym way out on the “sharp” end.   Dipping a dozen times or more into that chalk bag on the climate controlled, 30 foot plastic 5.10b / Gunks 5.8.
