JADWY you have to understand that SBA has gone through some significant problems with buyers in the recent past. Therefore, it is in his best interest to very carefully go through his prospective clients and weed out the ones that have red flags. Your negative reputation, combined with hot headed posts(for which the negative rep was given) are enough to give him pause. Selling lasers is not something we here do lightly, and he is using his judgement to the best of his ability to be a responsible salesman, and an intelligent, wary, and savvy businessman. It is nothing personal I am sure.
The good news is that the world didnt end in 2012, so you can begin to contribute to the forum, and as you do that your rep will begin to balance itself out. More importantly, as people see your contributions, you will be thought of in a more positive light and people will begin to agree to sell to you. Here is a positive rep of confidence that you have it in you to improve your standing here. +1
Thanks,
Isaac
