Unfortunately, I decided to create a petition using "Change.org
To my big surprise, my friends receiving the petition informed me that the website was asking them to donate money! (I never received that information entering the "my petitions" section...)
I did not give them the authority to make such a thing, neither they informed me about that intention...
And that's NOT ALL...
I immediately asked them to delete my petition, but I needed to do this several times, and many days after, until I finally saw my petition (partly) erased...
Stay away, they are scammers, use another company, more reliable!
