There is only one way to convert bad into good when, sadly, people who matter are not listening to this topic. When someone gets an undue neg rep, we give them a compensating positive one, may be we adopt a system that we get to read the thread where someone "allegedly" get a neg-reg-abuse, and if it really is undue, we compensate that victim with either 1 or 2 or more positive reps.
We device a system where a call is given and anyone who thinks he/she wants to give a positive rep to the victim goes ahead and gives one but read the thread first so that there is no injustice. That way, they will know that it's not worth anymore to give an undue neg rep to any member here. The madness will die down and we all will be happy.
A thread should be open where the victim will say he has been "attacked" and the related thread name will be given on that special thread. Then anyone can go in there and check the posts and find out if the neg rep was really uncalled for. If it was, then the member gives the victim a positive rep and says something like "compensated for an evil", whatever. Also put your name with the comment in the positive rep comment box so that any Mod checking/investigating will understand that it was done in goodwill. Or you can do it secretly too.
There aren't too many Jr-VIPs-and-above out there who are giving these neg reps (abusing is the word) obviously, so the Mods can also isolate them. At least we all would be assured that those "things" cannot hurt us any more.
This can go on until the whole system of "rep"ping is stopped all together.
I don't see any other way out, and may be Mods too would be happy that the forum is getting back to some sanity. They are working very hard but these "things" are getting out of their control too. I have tried to give such positive reps to the members in the past who I believe are victims... Hope you understand my concern here and think on these lines.
Lets clean this forum on our own of this particular uncontrolled-up-to-now mess. As you know, I now have sufficient positive reps so that those people cannot hurt my Rep much. And we would also help each other to get back easily what was lost.
The alternative is to always bow and kneel in front of them and gag ourselves forever in fear. Not any more now...
God bless us and this great forum. Beginning from this good thread itself, we start "beating" the "evil"

So call out when "attacked" and know that the help is available in plenty. Once we begin this good work, those culprits out there would also have the fear of getting caught by the Mods and banned for life, thus losing their money for no gains at all, and obviously it will hurt them very hard at their very soft spots.
Also, if I am thrown out, then you all can still continue the good work.

Of course you can still do the whole good work without being too obvious (silently) and thus can keep on doing this (giving +rep to the real victims) without any fear of whatever. It's up to you all to stick to doing this without waiting for others... it will benefit you all in any eventuality, so stick together.
So, OK?
