tag links (non-live links) is just a beating-around-the-bush method of posting warez. The intent is the same, and that is to pirate software and files.
I doubt KnownHost is out to make moral judgements about intent regardless of what you say.
Is mentioning the word warez allowed? What about telling someone to go to google and search for warez torrent? What about linking to a website that illegally distributes copyrighted items? All morally wrong IMHO. I don't see how it is against the AUP though.
The AUP states: "You may not publish, distribute, or otherwise copy in any manner any music, software, art, or other work protected by copyright law ..."
Does a link do any of those three things? In my opinion, no. What if I say mininova dot com, am I publishing, distributing or copying protected work? No.
In any event djloco, I'd submit a ticket to KnownHost support to get AUP clarification. That was you at least bypass the inanely biased people who want to shove their beliefs down your throat instead of answering your question based on the facts. The bottom line is their answer may coincide with what KnownHost eventually tells you, but the above posted did not attempt to answer your question, they only aired their personal opinion.
