This is based off of previous answers I've seen Squid give on these subjects, but I can't remember exactly
where these were said so if anyone wants to chime in with sources/corrections then Yeah go ahead!
1. I think Squid can look into anything if they need to, yeah, but they aren't going to be browsing through everyone's trades on a whim! I think there's some back-end tools that flag any potentially suspicious behaviour that they can then look into when needed.
2. The unfair trade rule is intended for instances of intentional deception on the part of one of the people involved in the trade. Two newbies trading cats that they want to trade without having the background of what may or may not be popular/valuable wouldn't count as an intentionally unfair trade.
3. As far as funnelling is concerned, a user quitting and giving away all their cats is fine! If you give all of your things to just one person then that might look a
little bit odd, and if you keep logging in just to send a friend all your stuff then that
would be funnelling.
