I guessed why my GitHub account had been flagged.

I want to know why my GitHub account got flagged.

　As I reported in my blog before What does "Your account has been flagged" mean? I mailed to github.com/contact. (RePost) - 一所懸命に手抜きする ,My account got flagged and got reset my profile public soon. To avoid the simillar troubles , I want to know what was the mattter.

I couldn't find the same case reported.

The message in my case

Your account has been flagged.
Because of that, your profile is hidden from the public. If you believe this is a mistake, contact support to have your account status reviewed.

Though I searched for the same casegoogle:"account has been flagged" AND github ,but I got poor result.

Search by other keywords - hidden,public,github

　I tried another search by the keywords - hidden,public,github. The words were from the sentence - your profile is hidden from the public . google:hidden the public github . And then, so-called　"not human problem" posts on blogs were found.

not a human message

One of our mostly harmless robots seems to think you are not a human.
Beacause of that, It's hidden your profile from the public. If you really are human, please contact support to have youre profile reinstated.
We promise we won't require DNA proof of your humanity.

Guessed by the people called "not a human"

I wonder that the trouble may be caused by mistakenly creating multiple Gists of the same content. (translatied into English)

Yesterday,I uploaded a text file of 26,000 lines to Gist via Gist.vim and got the message.

by Mr. Steven Maude

　from What happens when GitHub decides you're not a human - stevenmaude.co.uk

Perhaps creating several similar looking repositories (albeit with different code) in a relatively short space of time. These contain example code to access the API that we offer at work. Maybe it's because the commits looked similar, maybe because the commit messages or the commit content contained a URL. Who can say? what apparently happens is that any repository that's under your profile becomes a nice 404 error to anyone who's not you.

Reviewing my own Gist

　The message I received is different from the one they received, but both of the two things Steven Maude says match my case.

My Gists contain URLs

　 In my Gist codes,I mentioned the URLs of the sites I referred to.

Posting the similar Gists

　After posting a Gist, I noticed the rudimentary mistake and reworked ... revision 7.
　I was shamed of those poor mistakes, and I made another Gist as revision 1 and made it public.

　I don't know the SPAM checking logic.But I will be careful about the two points above.
