"No.Never because we never store your key.It just for sure that you are a steem user."
Bullshit, I'd be careful from using this app. The whole point of using steem is to be free form ads. You don't need the active key
You will be reported if you don't provide a better explanation
I totally agree, there is no need for any key in this app. Looks like a scam attempt.
They say "It just for sure that you are a steem user." but why would they care about that ? If the user is not a Steem user then too bad for him. Honestly, just specifying a Steem username is enough, there is no need for anything else. I wouldn't care if someone linked its revenue to my account, that would be free money after all !
Anyway, I agree with you that it's extremely fishy. I'm flagging it for being most probably a scam.
