You joined SteemIt before the hard fork. The hard fork was a copy of the SteemIt database.

PeakD shows posts from the HIVE blockchain. All of your PeakD posts are on hive.blog.

A huge portion of the install base has accounts on both platforms.

The problem is that people who join SteemIt or HIVE after the hard fork don't have accounts on both platforms. So, if you created a good HIVE account, an imposter could claim the STEEM account and trade on your reputation ... and visa versa.

If you have not changed the password on your account since the hardfork, you probably should. You should also change the recovery account on your HIVE account.

BTW, you have an account on the Blurt hard fork.

The password to your blurt wallet is the password that you had at steemit at the time of the hard fork
