Why is it marked as spam!! I did actually contributed :-(
Please remove the 'spam' label...

You marked me spam which may disqualify me for Hacktoberfest for no reason...
I am an enthusiastic open source contributor
I earnestly request you to remove the label, please.

I marked you spam because you didn't checked if this script was present or not. Its a general habit of a open source contributor to wait for a issue to be assigned before working on it. But you open the pull request without even waiting for us to assign it to you.

Sorry, I deliberately marked you spam for not checkout the repo first before contributing.

So sorry for contributing on the same topic. I did check the repo, but missed the existing solution.
Am a budding contributor, seems like good-first-issue went bad for me.
Going forward, will wait for an issue to be assigned before working on it.
But you marking me spam on Pull Request #395 too( where I did add a new solution) disqualifies me from Hacktoberfest itself.
( Any other label wouldn't have harmed so much )
Please let me be a part of Hacktoberfest.

Still in hopes of being back in hacktoberfest
