I was checking the profile. It did not post yet and last active session was July 20. There is high chance that someone entered their dirty hand and got the access. High profiles like this account should go through proper security check to verify the original users authenticity.
I think the forum adminstrators already took a look at it. Even they did not at beginning, after this topic was created for a while, perhaps they already did extra check on this account and its recovery process weeks ago.
There maybe need to keep google eyes on the profile. That's if after scrutinization and nothing was phishing because I see how difficult it's going to be to get this resorted since the user never made a single post to evaluate from there if it was the real Laszlo or kinda intruder that got accessed to the account.
Worse to it that the forum doesn't support Kyc that the admin would request for a rollover to confirm who's behind the scene.
It will be hard though if the legend destroyed the private key of the addresses he used.
Satoshi Nakamoto warned that Bitcoin users should never delete wallets they used and I think laszlo knew this reminder too.
If he has no intention to keep his past wallets, he can delete them or he just lose them somehow and I don't think it is too serious. If those past wallets are empty, he can lose them somehow or delete them by himself even there is chance of someone will continue to donate him bitcoins.
Sigh... why delete a wallet instead of moving it aside and keeping the old copy just in case? You should never delete a wallet.
Most users haven't been too concious with their Wallet address security keys at when they were beginners. So misplaced their private keys leaving them no accessibility to the wallets any longer. So, we don't expect to keep such wallets any longer as it'd be subject to waste of time or risks of we tend to use them further.
So it's important for a donor to also check on the wallets activities to know if the wallet is still currently actively in used before proceeding on the donation otherwise the fund becomes a dust to the wallet because he probably might have trashed those old wallets.
