what makes steemit special is the commitment you have to give when you click submit a post.

Everyone here whose having a good time is well aware of this feature that we love and is probably one of the biggest reasons, aside from the rewards, we are here.

You are more than welcome to edit posts within one month. I edit my bad spelling and grammar and mistake usually within a few minutes or hours after posting. Sometimes, rarely i go back a day, and fix things. I do this, as do almost every steemer, to every post we write.

If your post is more than a week don't expect anyone to look at unless its being referenced in a current post.

If you regret what you posted months ago that sucks but that's your commitment. If you were unaware of this feature before you posted than you should have looked up about the platform a little more because "no erasies" is not a secret.

Did you also know that the the version you wrote before the edit is also on the platform forever and people can see what you've changed and how it was before? So it really doesn't matter for older posts.

I can assure you, I and many others, have a bunch of posts we would like to remove from history but them's the breaks.

So always check your editing and content quality before you post. And then re read and check again right after posting, pay attention to the comments for the first hour in case someone makes a comment and you need to defend your post or say thanks for compliment.

IF you want to change and control history steemt is not the place. Try fb, twiiter, MySpace or what was that other one called Xanga.com .

Some people were straight up cheating and copy and pasted or claimed photos for as there own and made tons of money. Than one day some people whet snooping and discovered some user for months and months of cheating the game.
The cheaters tried to erase history but made themselves a FOOL as it only worsened things.

Not being able to erase is one of the features that helps keeps the rewards secure from cheaters.

Don't worry about any posts you have older than a month, really, no one else is looking at them and gonna vote 99.999% of the time.
