Firstly I’d like to thank Poker player that has notified me about this thread, LoyceV, you should have do it instead of him, but anyway, no matter about it.
I prefer not to send unsollicited PMs, and my assumption was you could (and should) have known about the red flags by reading their ANN thread.
I’d like to let you everyone know that I’ll close campaign within this evening and will refund funds to the owner.
That seems like a good solution

I don’t want to hurt everyone, and if someone risks to be scammed because of signature

I prefer to not work with this kind of business that risks to hurt my reputation built in 10 years.
I can't help but wonder though: do you research what you're promoting before accepting it?
@Shaker_finance
Since you're already responding to "some" of the issues/problems, it'd be nice to see an in-depth explanation as to why do you think signing a message isn't really that safe?
Are they thinking the private key will be exposed?
If so they can move some funds from address a to address b. However signing a message is completely safe.
My guess: they have no money so they can't sign anything and made up a lousy excuse.
I drive car worth around 150k$ lol
It's usually poor people who think other poor people are impressed if they mention large amounts of money. If you want bragging rights here: sign a message.
if you keep the funds for three/four weeks of the campaign, then it is safe there and there is no possibility that the participants will be cheated and not paid, right?
Right. But this isn't only about campaign participants.
also, the red tag which Shaker_finance received is still not based on the fraud that happened. even though he has a sordidness language, this should not mark him as a scammer.
The forum describs negative feedback as "You think that trading with this person is high-risk.".
