I'd say some of them are probably surprised to find out that a lot of atheists know their 'scriptures' better than they do.
The trolling probably confuses the hell out of a lot of them - along with getting caught up in the various strawman and other logically fallacious arguments (coming from all sides).
A few have undoubtedly come away with stronger faith in the veracity of what they have been taught to believe regarding 'god'.
And of course, some will start to question their faith in god.
Out of these, I would hope that they are doing it for the right reasons, and not just to fit in. I wouldn't consider flipping someone from christianity to atheism to be any kind of victory. It is my hope that everyone would want to learn all they can, and make intelligent, conscious decisions regarding their beliefs (or lack thereof).
APOSTLE PAUL SAID:
Colossians 2:16 Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the Sabbath days:
I DON'T HAVE TO ACCOUNT FOR THEM. LET GOD JUDGE. BE SURE YOUR SINS SHALL FIND YOU OUT.
The key word in your question is "view", I've never been able to view god. One thing all the gods I'm aware of have in common, they are all invisible. This is starting to not make sense, what kind of universe creator presents no evidence of themselves? So your answer is yes, I'm "looking" for a new religion, a religion with more profound "scenery", or any scenery at all. Why did He give us eyes if we can't view god?
Not at all, but they do come up with some good questions at times, which causes me to search the Scriptures and learn more.
I have also learned that people are very entrenched in their beliefs, one way or another. It seems our "belief systems" are more important than people are, and I hope that reverses.
