. If this happens again I think the ban should be permanent.
I dont think he was hacked *again*
From what I can tell, the OP was hacked in 2018 (or possibly 2017), the hackers posted malware links, not all the malware links were deleted, the OP was banned in 2018, was unbanned later that year, and was banned again just now because a moderator saw the malware links from when he was previously hacked.
Yes, I get that. But how can even the first (and most likely only) hack be proven?
The best-case scenario is he wasn't responsible to neither secure his account or delete the hacker's posts. Wort-case scenario is the account was never hacked.
