I have just posted my resignation announcement on Historum. The following is the copy.
I am resigning from Historum. I'm not an active member as I have my own site, All Empires, to contend with. I have however been a member for some time. It's no secret that you folks here have banned quite a few former active members, and that many of them have come to AE. Several have become important members and 2 were named as Moderators. To my knowledge, none of them have adopted new screen names and have come here with the intent of causing trouble.
In the last week, several of your high ranking members have seen fit to use new screen names and have made an effort to trash AllEmpires Intro section, by calling some of our members liars etc. One of whom is a moderator. If anyone had done this here you'd have banned them in a New York minute. I didn't ban anyone, but I am withdrawing my name from the rolls here.
I won't be associated with any org. that sanctions this type of behavior, and judging by the rank of those involved, it was sanctioned. You would think that with a site this big and this active, they would have better things to do with their time.
I don't think that there is anything more to be said.
