Doesn't seem like too big of a problem to be honest. Your forum email account shouldn't be something that is connected to your real identity anyways.
For some people it could be, i know people that create email accounts with a combination of all of their names, not that it can affect them too much, but it is somehow connected to their identity in real life.
Although, you've got to have faith in the forum and it's moderators to be of integrity and I can't say any have given us cause to be alarmed yet and that's to the best of my knowledge.
I do have faith in them, i asked this question to be sure, i wanted to know the reason why, and to know what function it serves, and to also know if it doesn't serve any function at all, of which we can then suggest for it to be removed, so it doesn't stop people who do not have faith like i do from making good reports.
I did a little search in the Staff section, and for the record the ability to send an email for each report was removed in January 2018.
There we have the answer to the question, it is all good then.
