What Tunicle said. Also shooting faction storage depots help to lower rep, but be careful with it to don´t lower it too much. There is not updated list of them unfortunately, little help is 4.86 guide for repping because some places are same. But some not.
By the way, you can find list of current restarts here.
I also sent you 3 million credits to help a little to finally fix it. Have fun.
