If someone gives you negative feedback then it will be seen on your profile if he / she is going to be a TT member and if the negative feedback he / she is not from two members then it will not be seen. If he / she is not from two members then there is no reason to worry.  If you are a member then you can tell him to pick up your negative feedback and if he does not give up then it is not possible to take it any more then it will be removed only then.  When he leaves the DT member.
