If they are inactive it is a bad deal since you will be stuck with it. It's really meant for you to get with other person and find a resolution.
But if they randomly gave you one not much you can do. The only thing I see is it looks like two of them are because you left them negative trust. Sadly right or wrong if you leave a negative there is a decent chance other person will do same to you.
But since not in default trust you don't show up bad is the good thing.
I got an untrusted negative trust from some scammer when I called him out that he has made a bitcointalk account using the name of a trusted localbitcoins user.
I was told at the time by tomatocage that it doesn't matter, as long as they are untrusted no one will see it and no one will care.
That seems to be true too, though I don't trade very often so maybe for someone who does it would.
Shouldn't this be in Meta?
