To be honest I am ambivalent about the reputation ability on FT to change members perceptions of other posters. At the same time though I am not ambivalent about abusers of FT in any manner.
Will having reputation available or not raise or lower the abusers ability? I think not. Will having a high or low reputation change my perception of one's post?
Realize that my opinion will be different on what the reputation of someone should be - after all I have a different life experience and will most surely come to a different conclusion than some. (Have to admit sometimes I agree with others.)
Simply put it is not going to matter to me one iota if someones reputation is high, low, on or off. They are going to have to continue to post in a manner that I find reputable for me to find them reputable.
