many people that are jealous or simply unhappy with their lives... will make fake disposable accounts and  put negative trust on people only because that part of this forum is unregulated.
there is nothing anyone can do because those who do this are very sad people and cannot be reasoned with!
red trust has to have a valid and provable reason behind it to show up site wide. and it is very rare that the newbie accounts can prove anything they say ... so they try and try again and again but it has no effect on those people who receive their way of attempting to taint the other persons profile.
