There is no validation team, however everyone can check the latest edits [1]. If there's a developed community in a ___location, say someone in your city, you can validate it yourself. Someone can use Notes feature [2] and report that the street has inaccurate information - by linking to some photo proof.
Thankfully many (not all, like POI) edits can be checked via satellite imagery [3], of which OSM has permission to use many - global ones being Bing, Maxar, Esri, Mapbox. With so much sources of imagery, the update rate is acceptable for most places.
All in all, the result is not as bad as you'd expect. From normal people I hear that OSM is "very accurate" (at least here in Europe). Oddly enough, nobody says anything about blatantly fake info, which indeed does very rarely slip, but apparently gets reverted.
Now as I am thinking, there is "validation team" of sorts, that's Mapbox data team, which uses OSMCha [4] to flag suspicious changesets and checks them (albeit not by physically going there).
