Disk failure isn't unlikely, especially with older drives and operating systems. But it could very well be an excuse, there's no proper way to prove that this is true. I'll have to admit though, Vod's rating on you is rather aggressive, giving the same rating to a lower ranked member would have been more reasonable, aside of that your password wasn't changed for a month's time (else it would be showing on your profile).
And according to that, I pose the following question to Vod:
Would a post from his twitter account verifying that he still owns it serve as appropriate proof that the account wasn't hacked?
It would provide proof that the account isn't hacked - but it could still be sold, which would mean a fraudulent purchase of trust...
The reason I left the negative feedback was for two reasons:
1) User knowingly edited an old message to appear he owned it
2) User claimed his wallet containing an address was lost when it reality the address wasn't even his.
Now #2 I could pass off as ignorant, but #1 is a clear sign of an attempted scam.
If he can prove he is the original owner of the account, I will have no problem removing the negative trust. But by viewing his PMs (which are completely different in language and grammar than his past posts), I seriously doubt it is the same person.
