Second chance is something that is scarce around here and those two people that left you a negative rating won't do it without justification which makes it even harder for them to revisit but they could if you can follow the advise given by @hillarious as that is the only way to appeal to them. I also need to blame you because it shows you have not been following the activities of the forum because if you had, you wouldn't have gone through that route and even to the extent of asking a DT member who their stand against such behaviour on the forum is well known.
