It happened to me too and not once. I wish I could say it is because of selling etc but better keep an eye on those asking to click a link to vote for witness. More than once this is the reason why the account is stolen.

I think it's a bit useless to ask those who rarely post to check their wallet frequently since they won't be around.

To recover accounts is a real pain and I managed to do so but I couldn't explain it to others. It will be hard too if the explanation is in English and you can't oversee the entire picture. I know for example on a phone it is not possible to see as much as those who are using a pc.

I hope it all will work out fine, I doubt this problem will ever be solved and it's clear the passwords used can be hacked too. It's no guarantee or protection.
