Pet peeve #3 are readers who throw in a bunch of cards with no positions or explanations and then read something vague and even unrelated like 'you'll meet a tall dark stranger' out of Queen of Cups, 5 Cups and 2 Pents. I try to explain each card as a reader because not everyone knows the meanings and certainly people can't know the personal meanings the cards have for me, so opening up the reading process makes it easier to understand why the reader came to the conclusion they did.
I'll agree that the ominous readings without explanation of how the reader came to that conclusion is absurd, but spreads without particular positions aren't uncommon, especially if one is using a TdM or historical deck. But then, those spreads are usually based on an open reading method, which places the left-most position as the past and everything else as after that, sometimes extending into the future (though not necessarily so).
I guess a new pet peeve of mine is very basic, but it's when readers don't look at the spread as a whole. They'll read card-by-card without really explaining any interaction or links between them. I find this happens a lot in the Exchange threads, which is one reason (out of several) that I've stopped going into that forum.
