Not quite. While I wouldn't trust a random stranger on the street with e.g. my money or private data. However, I have no problem trusting them to honestly and truthfully answer questions like "how do I get to X from here?" or "here, can you please mark my bus ticket in that marking machine over there and hand it back to me? I can't quite reach it in this crowded bus". On the internet, however, I don't trust a random stranger (e.g. a youtube commenter, or a reddit user) with answering "2+2" correctly, let alone with something that involves my possessions, no matter how low-value they might be.
