I will have to read this topic again, but as I see you mentioned account PDAngel, here is something to read, you will find many interesting information in this topic:
and there is this address
0x5aF75BF78984F3e22CFCCcB52BF62f529bCB440b which is used by both
PDAngel and
Mysterious1
I will probably start adding negatives to all accounts connected in both threads.
