The trust that I found that led me to this post (apart from my obvious circumstances) was left by yahoo62278 on Thule: "This user has some issues. Dealing with him may lead to personal vendettas or major smear attempts."
Seems fine to me. That is indeed a valid reason (of which there are many) to consider Thule to be untrustworthy. I fail to see any problem here, certainly nothing to conclude that the trust system as a whole is "broken".
