If you comment or post and no one upvotes it, it doesn't harm your trust ... it only means you won't receive reward for it. You don't get punished for it - simply not rewarded.

You mean writing posts about more niche and more out there content harms my own trust? That would apply to me as well, I made quite a few more offtopic and out there posts.

Comments deeper in a thread discussing something as well.
