Some signs:
Weird usage of tags.
Extremely poor/sloppy spelling and strange usage of interpunctuation marks (already in the title). (Yes, I spell badly, too, I know :-))
Self-agrandizing insistance on the relevance of the question, and more generally most forms of exaggeration.
Now that I try to write this I find it a bit hard to pin down the reasons. But, I know it when i see it.
