It would have bothered me as well, but I don't know if it is possible to avoid it 100%, I mean it's not possible to reveal right away a dishonest person. I believe that when you are doing your best that should be enough, I like to think that at some point everyone gets what he deserves, too bad for them but you in the end should just think of the people that like you, and they are so many, you can see it in the comments too! So remember that video of the Monty Python XD always look on the bright side of life... haha
