What Wrzhost / Worldstream (their own datacenter provideR) promise is ignoring intellectual property complaints. What they, in reality, do is ignoring the complaints until they get de-peered, or until the whining is accompanied by legal threats by entities based in NEtherlands. This happened and they "fled" (moved embarrassing clients and blacklisted networks elsewhere, possibly revealing some private data under strong pressure).
Spam, even in forums, is an entirely different issue, and I doubt they will protect your activity.
