This one of tbe reasons I created !dullsters@dullsters.net I do not have to worry about one instances modderation policy or splitting of users. Sure I could go crazy one day, but I have a robust ruleset in place that the comminity has followed without issue.

It costs me less than $10/mo to run mine and some of that is because I have to pay for an email forwarder until my hosting provider lets me start sending emails, part of that is factoring the cost of the domain name. The actual cloud server costs $5/mo right now.
