Sounds to me like you're here for all the wrong reasons, but to each his own.  You don't have a reputation, so the last neg you got didn't ruin anything.  Diks obviously thinks the project you're promoting is a scam, so he tagged you according to his judgement--and yes, members are allowed to do that. 

That's a risk you take with the trust system the way it is, where anyone can give negative trust to anyone else for arbitrary reasons.  I don't know a damn thing about the TOR project that was referenced, but you have to make sure that anything you associate your name with is on the up-and-up.  If it's not, you're going to get tagged pretty quick.
