It's plausible they record all transit through their single internet
connection to non-Singapore world. Here are my thoughts, sort of based
on https://www.torproject.org/docs/faq.html.en#Torisdifferent faq
This collected information could give them tor clients talking to the
public list of tor relays or known tor bridges.
They have deployed a DPI device that can recognize the tor handshake
and are recording the tor client to relay handshake.
In both of these cases, they can only identify that you may be using
tor, not what you're doing.
Using obfsproxy could defeat both of the above issues.
