Welcome to Steemit and the Steem blockchain =)
If you want to get more recognition and prove that you're not a bot, many users choose to do a re-introduction post later in there "Steeming" careers, where they include a picture of themselves holding a small sign saying their profile name.
Also, you should probably read the latter part of this comment I made on the introduction post made by @kadavy. Just so you've got some background information about "flags", or downvoting in general.
Yes i am not a bot, so it is possible to redo an introduction of my self in introduceyourself?
I'm not actually sure as I've not attempted this myself, but I don't see why it shouldn't work. It's however not entirely necessary to get it right. You'll still find plenty of followers here if you post good content.
A post named "re-introduction" or similar, that inclused a picture of yourself holding a paper sign with your name would be more or less required for a "successful" intro though.
Please get back to me if you've got more questions =)
