Question marks? At the end of statements?

[LoopyLoopsTootyFroots]

Presumably for those who speak with inflected intonation?

AIBU to cringe when I read this even more than when I hear it? (actual question for the last bit?)

Annoying, but I was wondering if you agree with me that questions ending in a full stop are more annoying. Can I sort of understand why they might end a statement with a question mark. Yes, because I think they are trying to indicate that the statement is open for discussion or to signal that they would have intoned. Wrong and annoying, but can anyone please explain why anyone uses fullstops at the end of questions.

YANBU. I have a friend on Facebook who ends every status, even if it's just something like 'is tired' with ?!?!? and another who ends every sentence he ever writes with ... They both drive me mad. Unnecessary and irritating...?!?!?

Are you sure they are not just asking a question?

[LoopyLoopsTootyFroots]

Not sure I've ever noticed questions ending with full stops. Have you. No, it doesn't work.

Allin - if they are asking questions, why don't they phrase them with question words?

I had a friend who used to end every sentence in an email with ??!!

She spoke that way in person too, sort of tentatively excited.
