"This struggle must be common here because attack on another is usually a function of a feeling of inadequacy inside. Steem's transparency makes it easy to compare with others and end up with a feeling that all we do is not good enough."
Unfortunately, around the internet, it is common to attack people personally when it would be sufficient to attack them logically.
As I'm sure you are now well aware, and speaking only from the perspective of the economic value of it as a business, your proposed account creation service was a bad idea. The service you were trying to create had already been done cheaper, and therefore better, by other entrepreneurs with even more community support than you had.
You also chose to give it what is clearly, in retrospect, a controversial name. I'm not bothered by it and neither was my girlfriend, but clearly some people are touchy about it.
Having successfully re-beat this horse, I can get to the point. It would have been sufficient to simply not use your service while pointing out it was bad in the comments without getting personal. I think automatically intuiting malice is jumping the gun. Obviously, the service was never going to make much money even if you left it running. Also, Paypal is like fraud central, so I can't imagine it would be much fun to operate this service either.
At the end of the day, I get why you made this post. I know people will (rightfully) point out that, to some degree, it is misidrection. However, what can we do when we screw up but try to point to what we do right? Our egos don't work well under attack.
