Well I'm not here to argue with you on which one is better, I'm just giving you my point of view and the way I see it is a notification as I suggested would help way more people than the auto screenshot cause beginners would not know where to report the screenshots, however notification could remind players to screenshot and link them to report subforum.

Also by saying lines of text I don't mean some text sitting on the side of your screen constantly. I mean it as in text that appears in your chat, with the "connected to..." and so on.
