Why not? It works similarly like in real life where many times you need to use your intuition & skills to differentiate between good & not-so-good persons in various scenarios with the only difference being in online world you only have the posts/online history of the person in question as the basis to go on. Yes you can say that you completely want to avoid any risks but doing that in real world is practically not possible without giving up on too many things so better trust yourself/at least keep your mind open to at least consider. Who knows, you might learn something (whether the risk taken succeeds or not) which may be of great help in real life later in future.
