What's wrong with this seemingly fine paragraph? It may look fine when you
you read it over hastily, but there is actually something wrong with it. It's not
not too hard to spot, and may surprise you if you are trying to read this over
over quickly without being as observant a reader as you really should be and
and not paying much attention. What is it?

The third sentence is not a run-on, but it has other mistakes besides the intended one (see lower comments). "It's not too hard to spot," need not be followed by a comma, since it is only a compound predicate. It's just a rather complex and awkward sentence that could be written better. But we all make mistakes; you yourself wrote a grammatically incorrect sentence in your comment.
