It's not impossible to come back from this @hamid.khademi but it won't be easy.

You're going to need to rethink your strategy. Obviously you've seen that the Steemit community doesn't appreciate spam.

Why not write about your charity? Let people know about what it's doing and let people decide if they would like to help.

If you put in some work, leave thoughtful comments and try to make Steemit a better place then the rewards should come naturally.

I hope you decide to turn over a new leaf & recover from the downvotes that you have received.
