A lot depends on the context of the discussion.

Here is the rub, you and I might have a different opinion about exchange 'x'
You think it's the worlds best exchange and see all these users using it with no problem.
I see a bunch of users who have had issues with it.
You keep telling people it's fine. I keep seeing bad things. You are going to probably either get a ~ from me or a neutral feedback.
Some people would neg you. It's a different view of what to do.

I am not going to red tag people for having different political beliefs or thinking alt coin 'z' is better then BTC but they are going to be ~
Other people think that pushing alt coin 'z' is worth a red tag.

I have done successful trades with people AND left them positive feedback who I have now ~ since I don't LIKE the way they do things and don't fully trust them. It's kind of a dichotomy BUT it tells the truth at lest to me. I did a successful trade here is that fact, but I don't trust them or their opinion, so here is ~ so other people have to make up their minds as to if they should be trusted.
