Why don't you just post a signed message with the address you mentioned to proved that you own the address not just posting any random address that contains a 0.5 btc on it. Or you should contact an escrow for the reasons like what posted above.

Firstly, i want to sorry if my comment make you uncomfortable.
- I saw that you are newbie, i advise you should rent a third party to run your campaign
- Payment for your campaign is too low, Legendary/Hero Members: 0.00006 BTC per post and Maximum 35 constructive posts per week so they can earn 0.0021 BTC per week. It's too low, i see that Legendary/Hero Members can earn at least 0.01 or above per week in most of other signature campaign.
I don't understand why some member still have joined your campaign.

Hey OP some of your signature codes are wrong.
Higher rank signatures are pointing to the .org domain, which is non existent.
Also Escrow the founds please. I would be interested to join this campaign but only with escrowed founds.
I have enough of being cheated, for such newbie account escrow is a must.

I checked out this section and it looks like the people who are running signature campaigns are legendary or have some of the green trust.

You have neither? Shouldn't you be using a middleman so no one gets scammed?

You must publish the codes of your signatures, also, it seems that the signature is very large and willn't look good in the profiles (Sr. Members / Hero/Legendary Members)

I'll delete this post once the changes have been made
