Happy to clarify some security and privacy points.
Sorry for misunderstanding your question, i'm not a native English speaker, i will try to respond as clear and easy as i can:

**Real but not liked answer :**

1. I want to say that you can trust me but whoever i am and have done, this won't make me sure. **In fact you can't trust anyone at 100%**.
2. **Steem and Github account are linked**, you can verify it GitHub, there is a link made (from GitHub) to the esteem8 Steem account.
3. **Code given is code shown** on GitHub, you can verify it on GitHub too. (GitHub is the server)
4. **The only way to trust code at 100% is to read it**, anyone can read it on GitHub and give his/her thoughts here.
5. To be sure that code **author are really these who are on GitHub**, there no absolute proof that i can give, however i can tell you that **the main contributor who's write 98% of GitHub content is the @primerz (on Steem and GitHub)  and is in reality Matias Affolter**. You can personally contact me on Facebook or by email, i will confirm it.  You can also check the domain name administrator (esteem8.com) on a whois service.

**I know that these type of answers are not liked because it prove that noting is sure**, (i think that you want that i respond "You can trust me at 100% because of...") but it is not the reality of things and i wanted to respond as right and close to reality possible.
Within the case that code where stolen from someone, the only way for he/her to say that his code was stolen is to say it here.

**Not real but liked answer:**
You can trust the code and me because of ...  Don't worries everything is fine (said in a sense that we think it's right).

P.S. Security is to know that **NOTHING is 100% secure** even Steemconnect, everything come from a purely personal trust on someone or group of people who are purely based on information that can be made in a sense to corrupt thoughts.
