Does the frowning face with question marks mean not a good post???

Was putting in for my 30 post for a month and seen 3 of my 31 post had this  at the end of them---the frowning face with above it---was wondering if that meant those post may not count or why it was there??--thanks

No, it has nothing to do with being a good post or not. Those faces are within your posts, so you must have put them in....maybe by accident. If you type three question marks in a row it automatically puts that icon in, so I'm guessing you did that.

OOOhh...I didn't know that 3 ?s in a row did that....lol....cool to know. 
Now I am curious of what other "typing tricks" are hidden among the forums.  lol
