It's come to my attention that this post is being misused by Hive account@dineroconopcion to justify asking for people's private posting key.

I encourage all users to treat their accounts' permissions and keys with care. This goes for any third party you may provide your posting key to. If their key list is compromised:

• your posts may be edited, defaced, or replaced with spam
• someone could post or comment with spam, scams, or resteem anything
• your vote power may be drained voting on things you don't want to vote on
• your account may follow people you don't want to follow

Though it limits potential economic damage to your account, the private posting key is still a key that should be kept private.
