@alexbeyman,
Friend this is not only for you! It happened to all :D But the problem is it effected you much much worst way! I can imagine how it feels you! Coz, when it happens to my small tiny comment I was pissed few times! So, I can imagine how it happens to your entire article!
As a result of this most of people now using Busy.org instead of Steemit.com! But according to me it's not the perfect solution! I hate to provide my keys to other sites as well :D Therefore, better save your writings before posting it! Like I do and before I post this comment i will do the same!

Cheers~
