While it seems that it is possible that what you were doing REALLY was "for the good of mankind" and possibly completely altruistic, I believe you went about it the wrong way. Don't you think simply starting a topic here in META might have avoided the panic created? You have to admit, the PM's did sound a bit "scammy" as you put it in the title of the PM, and the results, while possibly an overreaction, wouldn't or shouldn't have been totally unexpected.
The PM looked scammy but I guess it was "okay" after reading this thread.
However, imho this is absolutely not acceptable:
I was able to get access to SPQRCoin yesterday answering "1+1" with "2". No joke. He is in DefaultTrust level 2.
greenplastic gave negative trust to me. Now he is security locked for using "5" as answer to "how old was justin in 1980?". He was warned and had left this stupid question (answer should be between 0 and 99, the rate limit is one try per 45 second and IP address - in reality, you get a bunch of IPs and laugh about the limit).Proof:
https://bitcointalk.org/seclog.phpSecurity questions are a joke and should be disabled. There are members using questions with a probably secure answer or maybe even fake questions, but "1+1" is a joke. In case of greenplastic, he did not even understand the problem. We should think of who is member of DefaultTrust.
