Dun need to hire a lawyer.
The reason is very VERY VERY simple. In singapore, if you want to take anyone to court, the onus is on you to provide the evidence to prove that someone is guilty. No one is going to do it for you.
ODEX might have your IP, but there can be a very simple defense easily available.
1) If you are on wireless, ODEX have to prove that it is you who download it and no someone who taps into your network. Now, i am not suggesting that for those not on wireless to go and buy one set now and then delete all the anime completely from your harddisk and use this defense...
BUT then, imagine the amount of hard work that odex have to put in to prove this....case by case. AND it's not going to be easy. IF fact, if u look at it, they have to go by elimination, by proving that it's not YOUR neighbors who are doing it.
In the same way that if u hire out a car and a robber use it to rob a bank and escape, you as the owner of the car is not resposbilite, unless u knowingly lend it out for such a purpose.
Based on this alone, for ODEX to even bring you to court, they have to get this ready....and trust me, they dun have enough funds to do this to every one or EVEN one person for that sake of arguement
Which is why they are going for a scare tactic and trying to settle out of court.
