You should report that guy. I used your history to see who that was and I notice that he has a note on his profile about doing that. Chess.com has the move time data and can verify your claim that he didn't move until there were 2 minutes left. Throw him into the pool with the other Foul Players.
Yeah, but like I said, he can use his clock in any way he sees fit. He just used it really really poorly. It resulted in a useless game, but I don't think he broke any rules. And I'm just assuming his intention was to get a cheap win. There could also be tons of other explanations, however unlikely they may be.

I joined chess.com for tactic trainers and chess mentors. The interactive way to learn is way worth it.
For playing games, I think free membership is sufficient.
