Actually base on https://bpip.org/Profile?id=97501, there wasn't a time when this account was inactive before it got banned, I guessed this your time frame might be wrong.

@Xal0lex, this user might be telling the truth, I was able to get info on all the addresses this user old account used earlier before his claim hack 2015 from https://ninjastic.space/addresses?author=Scooby903 and none of the older address before 2015 were among the addresses used for the bounty cheating  https://bitcointalk.org/index.php?topic=2544574.msg37872632#msg37872632, but this may not hold solid ground because all except one of the older address before the claim hack was all bitcoin address. While when I try tracing through bitcoin Explorer I still couldn't get a connection between these accounts though more professionals to blockchain explorer may try to verify also.
