I'm just trying to help, that's why I'm vocal... Alena is 19, and she really doesn't understand much about blockchain and crypto. At the moment I don't have an answer to the question why the posting behavior hadn't changed, I knew about it myself only this evening.
I tried to convince her to change the wallet, may be it would help somehow. If she is using the one that has been sold with the account, especially considering the fact that there was no password change AND that it's not a problem at all to register on bittrex (while on steemit from Russia it really is. As from Ukraine too where I live. I managed to do it before the troubles started, but some of my friends didn't. So here I know something about the problem and can say that it's only possible if you use abroad phone number, for example my mom used her Hungarian one, not Ukrainian) - it can mean that it was sold WITH the account for a reason - for future abuse of a person who has lack of knowledge how to figure out everything. But still question here is - why she still wasn't robbed. If her wallet was used by someone else
