Maybe most of your online experience are from places with a different set of netiquette, but here at REN we are quite mainstream. If you search for netiquette, you'll find that it's very common to perceive caps lock as shouting. It may be something said in excitement (like your example), but it is still shouting and not talking with normal "voice".
As for swearing, I think you said F**K. That's not swearing technically, but it's no doubt what it means and I'd advice to no say it in every second post (not saying you do).
