Out of curiosity, does your hacker appear to be the same person who has/had a PD deposit address of 17YrFfqBFhxut9cBnLWjqVF62JGzoWySjP (2015)?
Also slightly off topic, but do you think this is in any way connected to the
recent hackings of several forum accounts? He apparently hacked ~10 forum accounts from the leaked password hashes that were leaked last year, and he apparently has a "vendetta" against you because he last "$10 grand" (50x $200). The timing of the hacks and the exploit match up to both starting at roughly the same time.
