You can't delete an account or activity on either chain. I don't fault or blame anyone that was taking advantage of the fork splitting and for most doubling their assets. So much happens on the chains it can be impossible to know what is going on in areas unrelated to where most users are having their experience.
If a person on Steem didn't know what happened and was still active over there while being here as well, i didn't have a problem with that. But, after all this time and it becoming more of a task to keep bouncing around url's checking everyone over and over it's easier to just remove folks from my curation options.
Anyone active before the hardfork for HIVE has a steemit account. It's the activity there that will determine who stays and goes here. But, i am going to really be generous with theh time period of amnesty and try to directly communicate the change to all those this might impact. Thanks for commenting and you have nothing to worry about. Cheers!
