So he's _REALLY_ embarrassed because someone online pulled a pretty hardcore prank on him. Yet he still continues to act as though she was a real person even after he found out about it?
Because if that is true, it makes it seem to the rest of the sports world that he's just trying to garner sympathy to win the Heisman. That kind of makes him even more scummier: the fact that even though he knows that he got pranked, he continues to perpetuate the lie.
Edit: for more context about it, read this: http://sportsillustrated.cnn.com/college-football/news/20130...
So it definitely isn't cut and dry, and I'm leaning towards extreme naivety on Te'o's part at this point (and possibly some embellishment to cover up embarrassment), although it definitely is a bizarre story either way.
The best case scenario for his credibility is that he was fooled, felt like an idiot and kept lying to prevent everyone from finding out.

Fakery on the Internet is fascinating and very very common. People fake having cancer; people fake their own situation; people fake their friends. The movie Catfish is a nice exploration of one person's fakery. (It would have been easy to say "OMG SHE'S MENTAL LOL" but it's a surprisingly gentle confrontation and you end up somewhat sympathetic to her.)
Here are some other notable fakes:

> Last year, an awkward high school senior in Wisconsin went online, passed himself off as a flirtatious female student, and conned dozens of his male classmates into e-mailing him sexually explicit images of themselves. What he did next will likely send him to jail for a very long time

> Followers of “Dave” on sites like Twitter and The Chive thought they were reading posts from a deaf young man suffering from cerebral palsy who had worked tirelessly to overcome his obstacles, all the while maintaining a positive outlook and relatably wry sense of humor.

Every time you give either time and/or money, you absolutely always could possibly get scammed so the only way you can deal with this is asking yourself if you for yourself and your own sake care and want to do something or if you will just quietly follow whatever story is being told and not let it mess with you.
If what you say is true and some forum posts could indeed "do lots of damage" then it is all the more necessary that people wake up and understand that they shouldn't just blindly trust people on the web, just as much as they don't blindly trust strangers on the street.
