Hi Rex! Sorry about the run-ins with the spam bot, I've restored your content, but have closed the other posts to maintain the thread here. With regards to how to report: Here is a great place, we've got some really active sleuths, and admins check in frequently!
As far as the malicious linking goes, (assuming this is the guide you're referring to) I don't see any direct links to phoneusa or phonepartsusa, and Witrigs has generally been safe in the past. The item page link has never been changed from the Witrigs link. It's possible that Witrigs set up some kind of redirect? Or that phoneusa may have done something malicious to their site? So I don't think there's any action that we need to, or can, take at this moment. But we'll keep our eyes open for future trouble from Witrigs!
For reference the other questions' content is as follows:
