30  Bitcoin / Project Development / Bitcoin Bounties to catch the crooks! on: September 16, 2014, 06:34:41 AM is now live.

Now anyone can contribute bitcoins to motivate people with information on criminals to provide that information to law enforcement,  or motivate law enforcement officers to take action directly.
I've personally contributed over 40 BTC for the bounties to help get things started.
With this financial motivation I hope we can help catch the dishonest among us,  and motivate those working in law enforcement to actually take action.

I'm sure there is lots of room for improvement to the site's aesthetic and technical implementation.

Please post your suggestions for improvements to the site below. 

Together we are making a better world!

I'm sad to report that has encountered our first scammer:

******Contact details removed until things cool down*****

He ordered a video card earlier this week,  but insisted that we declare it as $0 dollars for customs.
Legally we are not allowed to do this,  so we offered to declare the full amount,  or refund his money.

******* asked for a refund which was promptly sent.

Unfortunately an extra 4.5119 was also sent to him that he is refusing to return. (I understand that this is partially Bitcoinstore's fault)

The Bitcoin address and payments in question are:

He has refused to refund the money when asked via email,  and when I called on the telephone,  he hung up on me as soon as I told him my name.

Other than the reputational enforcement from this posting,  I don't know what else can be done.  

Any ideas?

BitcoinStore customer information is normally considered private, and will only be divulged in cases of blatant attempted scamming.
Because this order was placed with Bitcoin,  we have no idea if the above is his real name,  
but we can assume that the address is valid,  and I know that the telephone number is valid as well
because when I called him,  he knew exactly who I was, and why I was calling.
39  Economy / Service Discussion / Thank you Instawallet for being such a great online wallet! on: December 06, 2012, 07:08:10 AM

The below problem has been resolved.
Thank you Instawallet!

It seems that someone is trying to attack

There have been more than 50K new wallets created in the last few minutes or so.  (From less than 2M to over 2.05M )
If you watch the page,  the number of wallets is increasing faster than the eye can follow.

My recent instawallet deposit has also not been credited into my account.

What is going on,  and what can the community do to help?

(If someone knows the owners,  please contact them)
