<human>: We have been together for eight months. He is really quiet and laidback, and well-mannered, which are qualities I like in him, but I saw something that is making me question what I know about him. It started when he emailed me a Starcraft replay that he played and I noticed him using language in it like "faggot" and "cunt" at parts of the game. I also notice he has sites like that on his bookmark (I don't need to name them, you know them), and when I looked on his computer on reddit, his user name has a lot of trolling comments that had a lot of negative downvotes. I'm wondering if this is a deal breaker, or if I'm looking too deeply into it and it's not a thing I should be concerned about.

Can you summarize the given text in a few sentences?
<bot>: Discovered my boyfriend's internet activity is not very clean, he trolls, uses bad language and behaves immaturely. This is the total opposite of how he is in our relationship. Is that the real him?
