There needs to be more done to crack down on the hackers even if the instances of hacking are rare just because even one hacker ruins the balance and creates an environment where every one is assumed to be hacking. A couple of things I have seen recently that may be hacks or just bugs being exploited...
1) Stealthers planting, capping, or picking up the Huttball while stealthed.
2) Someone planting in Voidstar from the other side of the door.
3) There are definitely a few moderate speed hackers but when a second or two makes a difference that's a lot.
...overall it's not a plague but it really needs to be tightened up.
Another thing I've noticed is that actually may be a bug is the resolve system:
No resolve but no CC
Full resolve but getting CCed (sorc CC)
This may be a bug but I know a few resolve hacks exist first hand.
