So basically, anything that is beneficial and helpful to the growth and betterment of Goldcoin is not only allowed and encouraged, it's essential to the development of the currency. This includes constructive criticism.
However, there is a tendency for longtime users of BCT and others to arrive and mistakenly take this as a no-holds-barred free speech type platform. And then there are the trolls that arrive on TOR networks playing various games intent on distraction, disruption, and inciting drama.
If I do my job correctly, most of these problems are handled quickly and pass by unnoticed by the general community. Before banning a user I take into consideration his age, network of origin, history, and other factors. But post moderation and disciplinary actions are not exact sciences and occasionally a community member can fall victim to collateral damage.
If you feel you were unfairly blocked or banned (there are only 8 total and some of those are multi regs) please send me a PM.
It really doesn't matter how many accounts this guy/girl opens. It's actually having zero impact on the coin's success.
