Please help!! @shadowbot

Hi fellow steemians!

I need to remove my account from the shadowbot system. But I am unable to remove it myself. I know some old procedures.

First of all I changed my password, thought it will automatically changed my private posting keys or etc. and I would be removed. But it didn't worked.

Then I tried to remove it by its site "shadowbot.us". I logged in and gone to settings section. And there is an option or dialog box of remove your account. You just need to provide your current private posting key and then you need to hit the delete my account. That's it.

But it also didn't work.

Please suggest me what should I do now.
