I strongly suspect it's torrentz.eu doing the blocking.
If I run traceroute on 185.87.147.3 from EC2 I get:

And if I run that from my local machine I stop getting replies at step 11 too.
However if I inspect the traffic from EC2 via wireshark I get:

I don't think AWS would have a strong incentive to block these sites seeing as bandwidth is pretty expensive, but these sites would definitely have an incentive to block scrapers being run by AWS customers.
