Appreciate the concern, and we hear you. We're still investigating this particular case. Normally we'll catch these types of spoofed emails. What we need to do is refine our system.
To be honest, we haven't had many complaints about spam emails or spoofs -- it literally never happens, otherwise we would hear about it all the time. We answer every help email we get -- so we have a decent idea of what our users care about and what pains they really see.
If trust is an issue, we will fix it.
